Great idea to create such a channel. Many talk only about rigging it up, and 4wd are becoming more and more popular, but actually not many do grow a genuine knowledge along. This channel really adds to the 4wd community.

I run independent front suspension and solid rear diff in my 4wd and I love it. I don’t do stupid tracks. I hit ruts and sand but lots of gravel, I tow my camper trailer a lot and other trailers. My car handles it fine. I’ve got no need for a solid front diff.

[@MadMatt4WD]

And that’s the important thing. We all have different needs

[@dantrucker7623]

MadMatt 4WD I’ve looked at live axle vehicles in the past and I’ve driven them but I’ve always owned ifs 4wd’s. I’ve done stupid hard tracks and full on winch fest tracks in my cars and handled it fine. I’ve got a pajero now that’s ifs and it goes everywhere and does what I want to do. It’s my family car, play car, Towing vehicle and my touring, camper towing rig. I love my 4wd. Ifs setup has never failed me. I’ve broken cvs and shafts etc and have it fixed in a day. I’ll regretfully if no other choice buy a live axle rig but for me it’s IFS all the way.

Solid axle everyday of the week. My Suzuki Sierra is 25 years old and has been off road all around Australia with not one axle issue. Great topic Matt 👍

[@MadMatt4WD]

I love the zooks

[@RMTCTL]

Thanks for the video, Matt! Great explanation! I have a Jeep XJ with solid axles front and rear and I love how it works both on and off road. Yes, it's a bit "trucky" driving it on smoothly paved roads, but it's really nice off the roads because of that constant ground clearance. It's pretty much impossible for me to hit the bottom of the vehicle on the ground if the axle doesn't hit it first (barring some weird breakover situation). Also, the Dana 30 and 44 front axle in the Jeeps does not have CV joints at the ends (in the XJ and the Wranglers - not so with the Grand Cherokees). They have standard U-joints at the steering ends of the axles. This does require some additional lube and care, but generally, they are stronger than CV joints of similar size. I love watching your channel and was thrilled to see you work with Matt's Offroad Recovery earlier this year! Stay safe! Keep the shiny side up! Cheers!

[@jackar1ah]

My prefence is solid front axle and my daily is an LN106 HiLux, so leaf springs and solid axles all around. However, I have driven a few other LN series IFS Hilux variants both on and off road and have noted the following differences: Having the diff tucked up out of the way and a bashplate under it on the IFS means the front end is more likely to slide across the ground rather than plow into it like a solid axle's pumpin does when you bottom out The solid axle version stays more level when crossing ruts at an angle as the extra travel and effect on the opposite wheel means one side doesn't drop in as much as an IFS one would Ride and handling isn't great on either variant, though the IFS versions do corner better as they an anti rollbar in addition to any benefits the IFS gives Wheel alignment is more easily adjusted on the IFS versions, so tends to be easier to knock out of whack, where it is more set and forget on a solid axle... Overall capability is determined more by other factors such as tyres and lockers in many situations... On a general note, I've also noticed that solid axles have a certain amount of passive steering inherent to the design, as the movement of the shackles on a leaf spring system, or the radius arms or equivalent on a coil system, pull the wheel back or forward depending on what point they are at in their range of travel....on IFS this variance is in camber, which in general seems to be more manageable in terms of handling....

[@MadMatt4WD]

Great comment

[@rockymountainjazzfan1822]

"The solid axle version stays more level when crossing ruts at an angle as the extra travel and effect on the opposite wheel means one side doesn't drop in as much as an IFS one would." This is a very important comment. I can take my SFA vehicle over an off-camber spot on a hill with little drama, but when I take my IFS vehicle over the same spot when one front wheel drops into the off-camber portion, the vehicle can come close to rolling. The most common solution to this in an IFS is to substantially stiffen the front springs so that the suspension acts more like an SFA--of course, the ride and highway handling are considerably less pleasant.

[@sherman4970]

Got a Swb mk2 pajero and have had zero problems with suspension.

[@MadMatt4WD]

Good thought. Thanks

[@Catboy-hr2qp]

Great video! Only thing I think that wasn't mentioned but is more for the serious off roader is that the solid axle in the front greatly benefits from a locker since it's far easier for a wheel to come off the ground vs an ifs where as the ifs doesn't benefit much from it and it'd only add more stress on the cv joints

[@MadMatt4WD]

I don’t actually agree with that though. Both benefit from a locker and an ifs can handle a locker just fine so long as the driver understands how to use it correctly.

[@AiDOS__]

@@MadMatt4WD agree 100%. Also would say that a front locker in ifs is more important as they tend to do pretty impressive wheel lifts constantly and that shock load of a spinning tyre hitting the ground to a stop is what's going to break that cv joint pretty quickly. I've done 2 cv joints before like that and put a locker in and haven't broken a cv since.. could also be down to more careful driving as you get older too 😅👌

I wheel a long travel Xterra (think of it as a cheaper cousin to the Patrol in the US and it has IFS/Solid rear) and it's been fine for me but now I'm moving on to an 80series LC and I agree with your points. The IFS handles better on road and has more comfort but I've broken multiple IFS pieces offroad. Reliability is important to me and that generally is where a solid axle shines.

[@MadMatt4WD]

Cool

[@JDKing-rj2oy]

This seemed like a very unbiased comparison Thank you!

[@milesabove5259]

Live axle is better for low speed off road. IFS is better for high speed off road. Obviously upgrades can be made for both, but that’s pretty much the basic rule.

Congratulations! For almost the first time in any off-road articles or videos that I've seen, you accurately described the ground clearance issues with an IFS. I own 4WDs with IFS and SFA suspensions. For hard off-road use, I greatly prefer an SFA front suspension. Sadly, here in states, the only new vehicles available with SFA are heavy duty pickups and the Jeep Wrangler/Gladiator. Sadly, the Jeeps have some pretty serious reliability issues aside from the SFA.

[@MOTO809]

I bought my 93 Yota pickup 14 years ago. I needed a pickup for work and I knew Toyota had a good reputation. The IFS is very nice for all the freeway driving I've done over the years. However, anytime I have to cross a ditch or wash diagonally, the IFS flexes out and I'm left teetering with no drive. I cured this by installing a rear air locker, but I've watched stock Jeep Cherokees drive through the same obstacles with no issue. So, like you said, solid axles are the way to go if you're doing anything more than a dirt mountain road.

[@MadMatt4WD]

Yes.

[@MOTO809]

@Artemio Medina not all ditches and drainages cross the road perpendicularly, so you have to cross at an angle. If you have open front and rear diffs when you teeter, the 2 wheels that are dangling in the air will spin and no drive will be applied to the 2 wheels left on the ground. At that point you're stuck unless you can lock one or both differentials to apply power to the ground.

[@MOTO809]

@Artemio Medina There's always constant drive to the rear whether in 4WD or 2WD.

[@SPNKr02]

@Artemio Medina the center lock forces power to front and rear yes, without lockers in the differential, power goes to the tire with least resistance, ie the one in the air

[@lk6912]

Canadian here, any of you Aussies run long travel kits on your ifs trucks? Lots of fun at high speeds but you can keep 4x4 by getting extended cv axles, and control arms which improves your angles.

Am keen to do more testing on some tough tracks to see how it goes but thinking of selling to purchase a solid axel. Seems they will be a thing of the past..

[@robertWohlers]

Matt... A very fair assessment of a solid axle and an IFS. I agree totally with your pros/cons points made. Well done! My PowerWagon, with its proprietary "Articulink" solid front and rear axles, breaks the basic concept that this type of suspension system is less comfortable on and off-road. The PowerWagon completely rides like a Lexus on the highway and is very smooth when riding at faster speeds on corrugations off-road. My Jeep JK and TJ coil sprung solid axle vehicles are more representative of a rougher ride on the highway than an IFS vehicle.

[@MadMatt4WD]

[@practicalnottactical]

I own two 4WDs, an 80 series Landcruiser and an IFS Hilux, both have mild suspension upgrades, and I can say without a doubt that the live axle Landcruiser is a far more capable vehicle on bad gravel roads and going slow through difficult obstacles. The IFS is a compromise, there is no compromise with coil sprung live axle vehicles. The Hilux is still a great vehicle, I just cant expect it to keep up with the Landcruiser.

[@MadMatt4WD]

I’d agree with that

[@WhyWouldYouDrawThat]

Really good explanation. I had most of that in my head previously. But it’s helpful to have it confirmed by an expert 👍. Our MU-X is ute based, IFS front, solid rear. Not perfect, but it came out on top for our requirements. One of these was we could buy it via lease. Right now there are very limited options for solid front from new (or near new). Our plan right now is the minimum to go 95% of places. Quality off-road AT tyres, snorkel, bash plates, recovery points and gear, hand winch, roof rack and recovery boards. We are also considering a $600 front auto-locker. We’ve actually done quite a bit of off-roading with a stock setup. So long as the tracks are dry and the tyres low it’s been awesome 😀 With careful driving and track selection, we feel we can avoid the following, at least initially: Bull bar, rock sliders, electric winch, suspension lift, engine mods. Interested to hear experienced thoughts.

I switched from a solid axle to IFS. While I don't regret it for other reasons, I'd prefer to have the solid axle back disregarding all else. I switched from a Jeep XJ to a Toyota Tacoma. The only things I really miss from the driving experience are the solid axle and a real shifter for the transfer case. I have always been envious of the Toyota selection (or 4WD selection in general even) the rest of the world outside of North America gets.

[@billroach2393]

I think you've nailed it for the most part. My Chev Silverado 3500 has IFS in the front and I have a 4.5" lift. However, the CVs still sit perfectly level/flat at rest due to the BDS kit incorporating a full diff drop of 4.5" too. Same thing with my previous vehicle; a 2006 100 Series 1HD-FTE, in which I had a 3" lift with diff drop to keep the geometry just right. My days of hard wheelin' are behind me and at 65 I'm looking for more comfort and power than offroad capability. Like you said....horses for courses.

Benny the air suspension I run is airbag man coil bags. Easy install into the coil springs if you don’t run coil over shockies.

Awesome content as always Matt! My 2c from IFS experience. In terms of KUN Hilux and PX Ranger vehicles the genuine CV’s are stronger and more reliable then their aftermarket counterparts. I use genuine 2nd hand CV’s from all four x 4. Many people have had a hard time with aftermarket CV’s. A good quality diff drop will help with re-aligning geometry and de-stressing CV’s with a lift. But let’s be honest solid axle is king anything else is a compromise 😉

What about IFS, IMS and IRS suspension of Pinzgauer. Has no inner CV joint. And IFS CV joints only pivot while steering.

[@MadMatt4WD]

Ifs cvs work work with suspension and steering.

[@lowellcrabb151]

You didn't mention the advantage of traction on the ISS. Ag tractors have been calling attention to that for some time. The tires are always flat on the surface.

[@MadMatt4WD]

Yes but in an offroad situation I don't think that will have a big bearing due to the surface always changing shape. For tractors for sure it would be a factor. Also airing down allows the tyre to form to the surface.

[@lowellcrabb151]

@@MadMatt4WD You are correct on that point. Keep the information coming.

Hi Matt I found your video very helpful. Would you think itt would be possible to swap the front IFS axle on a 10O series land cruiser to a solid axle?

[@MadMatt4WD]

Not without significant work.

Comfort also comes back to wheel base. What rides better? Your 105 Landcruiser or Suzuki Jimny ? Both live axle

[@MadMatt4WD]

Well that's one factor. In my case, we should use the 105 or the Bundera :)

[@sydneymowerandautomotivece4319]

@@MadMatt4WD ya true, how could I forget the Bundy. The further apart the wheels the smother the ride, but then smaller the ramp over angle. Just most systems in a vehicle, there's more to it than a few parts.

[@sydneymowerandautomotivece4319]

@@Matthew_Australia my comments on wheel base was based on MadMatt's comment about the 105 being smother than the Hilux. If you want all things to equal as best as possible you should compare a 100 and a 105. Same vehicle just IFS or Solid front. Was just adding to the conversation yes another factor, but a factor that changes the ride quality more than suspension system.

[@MadMatt4WD]

I believe I alluded to them at in the video.

[@harveysmith100]

The only way to truly test the comfort comparison would be a 100 series verses the 105 with the same suspension as far as possible. Interesting to see the new kid on the block, the Grenadier has gone for two solid axles, the right decision in my opinion.

[@MadMatt4WD]

Yes I think that would be the best way to do it but both vehicles need to be very similar in weight and setup.

[@MrErViLi]

Could you do a comparison of independent geared hubs like in military humvees and portal axles like in unimogs?

[@MadMatt4WD]

Probably not. I don’t own any of those.

[@cocomartens89]

Any advise why my new 70 series with solid axle keeps on pulling right, my only upgrade is a koni havy track suspension. I’m driving a vdj79. We tried tire pressure, and a lot of visits to the wheel alignment center, but just couldn’t figure it out. The tires are basically not also the problem since we tried to swap it already from other sides. Thanks Matt! Love your videos

[@MadMatt4WD]

Check the brakes aren’t dragging. What side of the ride do you drive on. Most roads have camber and a vehicle will be set up to compensate for that. If you vehicle is designed for a lhd road and your on the right this could be the issue.

[@cocomartens89]

@@MadMatt4WD hey Matt! Just checked everything out, I tried swapping the 2 front tires out to a bf goodrich km3 and then the pulling to the right was gone, it it kinda transferred the pulling to the left side, but kinda tolerable compared to the previous pulling on the right, I’m currently using the toyo tires open country m/t. Then tried googling if there’s been issues correlating this model of tire to pulling on the right, luckily enough there has been a lot of articles saying that open country m/t owners are also experiencing the same problem. Could any of this so true? Thank you Matt! Could there also be faults from the Koni shock absorbers or just plain tire model faults? Cheers again. 🍻

Wild to think that the center of the vehicle compresses due to the independent suspension.

[@MadMatt4WD]

Yes. Watch for it when you see one Offroad.

@@MadMatt4WD I got my mom doing foot exercises to heal a bone spur on the top of her foot! I explain by using a rolling spike thing - it stretches the bottom arch to reverse the compression on the top of her foot. I tell her that is the root cause of the bone spur. It is working. haha.

[@MadMatt4WD]

There are a few around but not common.

[@MicksGarageDarts]

I own a 2002 Gen 3 NM Pajero, this is the first of the IFS/IRS range with the Gen 1 & 2 being Solid rear with IFS and the Gen 3 & 4 being Independent all around. Personally I love the Pajero for its ride and handling both on and off road. I dont do large ruts and hill climbs but am not afraid to put a wheel in the air. Also I dont drive flat out at harder obstacles although there have been times Ive hit a wash out across a road a bit too hard. So far all Ive had to do suspension wise is replace the shocks and springs because they were old and worn, it is an 18 year old 4x4 after all. Ive had no issues with CV joints or any other part of my suspension/axel set up. I do have repairs to do on my power steering and have had to replace hubs but again it is an 18 year old 4x4 and it has been used as a 4x4 through mud, sand, dirt etc.

[@MadMatt4WD]

Nice one.

[@de-ka]

That was a great explanation!

[@MadMatt4WD]

[@TheVeganTravelShow]

Which type of suspension is more comfortable on corrugated outback roads, like Tassie’s west coast?

[@MadMatt4WD]

Coil springs are the most comfortable

[@seanyeek8601]

I have own a Hilux too, it's year 2001 truck. It's feel more comfortable when I went to off-road. But, the cost to buy the spare parts were more expensive than live axle because my hilux has upper and lover arm ball joints, lower arm bushes. so, that was the cons

[@MadMatt4WD]

Great points.

[@Ed-wy2di]

It also depends on your budget and how much you intend using it for everyday driving.

[@MadMatt4WD]

Absolutely.

[@BuildSomethingAuto]

Thoughts on TTB? Thats what I decided on for my build. I might be biased but seems to me it has most of the advantages of both IFS and solid axle ;) . And if you endup with dana 50 ttb out of a 3/4 ton truck, but on coils....

[@rockymountainjazzfan1822]

I've owned a couple of TTB vehicles. Depending on how you look at it, TTB is either combination of the best features of SFA and IFS, or a combination of the worst features of both. TTB is more rugged than IFS, but has more unsprung weight than an IFS. TTB handles better on the highway than an SFA, but worse than an IFS. TTB is easier to lift than an IFS, but more difficult to lift than an SFA. TTBs can be difficult to keep aligned properly, compared to either an IFS or SFA (my TTB vehicles always wore the front tires excessively, even when properly aligned--a very common complaint about TTB suspensions). TTB can suffer like an IFS with decreased center ground clearance when the suspension goes into compression. About the only solution (as it is with an IFS) is to stiffen the springs sufficiently to decrease the deflection, but that also hurts ride quality (just as it does in an IFS when the springs are stiffened).

[@BuildSomethingAuto]
