GMT400 Dana 70 axle conversion is DONE and it's AMAZING! Wider is Better

[@dwaynerozier2422]

Hey LT. You are doing a great job with your videos. I want to give you some advice. I'm a physical therapist and constant kneeling on your knees without protecting the joint, will lead to injury. People who do carpet installation would never do a job without good knee protection. Please add a good set of knee pads to your tool collection. Take care of yourself, so we can keep watching your videos.

[@kleimbach77]

I am a Ford guy but I am loving this project plus it doesn't have the ad within the show like truck tech did subscribed!

[@bbruno1266]

I’m in love with that burban... I have always despised how GM made the track width narrower in the rear. Money well spent on your part in my opinion

[@artysmotorsports]

Always wondered what you could do about the rear tires being sunk in so much. Thanks for clearing it out brother 🤘

[@austindoud273]

That's supposed to make them drive better

[@shadowopsairman1583]

I thought GM was using the 10.5/11.5 AAM 14 Bolt GM rear with disc brakes in the 3500 in 2005

[@patrickmoran8790]

On you GM 14 bolt and the Dana 70, the u-joint size is 1350 series. You can get a new pinion yoke 3-4-5731-1x, and strap kit 3-70-28x for the Dana. If you pull the yoke, install a new seal, and maybe a new pinion nut. On final installation when filling with oil, it needs that stinky posi additive. Dana 43161 or ATP AT-210. The clutches in that Pow’r Lock will pop if you forget the additive. I have found the additive in the blue toothpaste tube doesn’t work as well in the posi diffs I have. Driveshaft length for a slide-in slip yoke transfer case should have the slip yoke approximately 1 1/2” from being bottomed with the vehicle at ride height to allow for suspension travel while driving.

Working on the Burb in jorts... instant 👍🏻👍🏻

[@bigc7t]

the should have came from the factory like that......Looks great and mean and tough....awesome job

[@erichildreth7562]

It really does look a lot better!! Once the brakes are all fixed and working good it should be a lot better!! Nice work!!

[@tylerhensley2312]

The 14 bolt is twice as strong as that Dana 70 specifically because of the 3rd bearing on the pinion. The reason the 14 bolt got shelved by gm is because of its weight and there are more parts to manufacture. I would have done a brake swap on the 14 bolt and stuck some spacers on it, but that doesn't make for good teli. Keep up the good work!

[@LawrenceTolman]

the Dana 70S was used in vans that had a GVWR up to like 12,000lbs in some applications, so I think it will be plenty strong for this application, but the pinion nose support bearing is a nice touch on the 14b

[@casualobserver1663]

Nice upgrade I love factory upgrades and mixing and matching ,

[@ovlraglvr]

That was an expensive way to satisfy your OCD. 😂

[@LawrenceTolman]

yes, it was

[@Terk131]

CHEVY/GMC have been staggering Trac widths since making 4x4 trucks. Reason is the engineers wanted the the rear tires to dig into fresh ground for better traction instead of following the track the front tires and the loose dirt made from the front tire. Plus back in the day the front and rear pumpkins had limited slips and or lockers and they really dug in. I thought about this conversation for my 98 diesel suburban but I have the G80 locker and running 285/70/17's and it looks good. The ones in the next generation that had the quad- steer had the rear tires out but looked "off" to me.

[@richardharvey8939]

Love the videos. Back when those trucks and the corresponding suburbans were new. To fix that issue we bought Alcoa’s with different back spacing to correct it. We couldn’t rotate them anymore but they looked better.

[@curvs4me]

Awesome fix!! Now I know where to get it. Wheel spacers are the worst. Big offsets on the front wheels are even worse making massive scrub.

[@johnstephens7697]

I love the fact that you are very particular about things! I'm Extremely O.C.D. and even aggravate myself at times but, I was raised to do once and do it right and enjoy it! 97% OF people would've done the wheel spacers and took the cheap&dangerous way out. That's why I enjoy the real 3% Percenters out there in life! Sincerely: Stephens Motorsports Family

[@RadggsAutomotive]

The change gives it that Secret Service profile.

[@oltrucksrule]

I always thought the same as you. Been bugging me for years. Glad to see you done it!

[@DavidJames-wz3mf]

I completely understand the difference between front and rear wheels being offset bothering people. But in a 2500 suburban with the 454 big block with 4l80 transmission it's hard to give up that 14 bolt full float rear axle especially when plan on doing solid front axle

[@williamdon3442]

It looks meant to be. Good job sir.

[@GeorgiaHyway]

Another AWESOME build! Being a welder/fabricator myself? I love watching a project like this come together. From what I can see? very nice welds on the perches and the shock mounts. Keep the great projects coming because I'm definitely watching!

[@joshck93]

Love your Suburban build. I also have a 99 k2500 with the 454. I would like to do the transfer case swap on mine someday.

[@goatlord6255]

I honestly didn’t think it would look much different with the new axle, I was wrong! Big difference! Way to go Lt!

[@LawrenceTolman]

yeah, its amazing to me how much different it looks with such a little change

[@tysoncurrie7745]

I have a 1996 2500 Suburban with the 454 and 4l80e trans as well and want to do the same exact same thing to it that you did instead of spacers. On my Suburban I upgraded the hydroboost to a 2021 hydroboost and man it makes a huge improvement on braking assist and almost feels like a newer truck besides still having drum brakes in the rear which I hope to eventually change to disc with doing this conversion in the future love watching your channel on things that have been bugging me about my suburban as well, was sad to see the Suburban go.

[@cesargallo7424]

Beefy axle for this old lady. Looks much better this way

[@fakename2481]

I've got to say that I really like your content. Did you spend too much? Not if you can still pay your bills and meet your other commitments. I'm not a Chevy guy but I like the new look of this rig.

[@bigredracer7848]

2👍's up LT thanks for taking care of are need to see work being done

[@bigredracer7848]

I have a 2001 Chevy 3/4 ton suburban the last thing I'm worried about is how far the tire stick out underneath the underneath the suburban I pull I didn't close car trailer with a 1974 firebird with a 565 Big block in it for drag race and then the 6 L was getting tired so I got another lq4 and turned it into a 6.7 L for those of you that don't know the math that's 48 cubic inches I added 44 cubic inches 2 my 6 L now the 4L80E works like it's supposed to going up a hill pulling the trailer and drops in the drive finishes the climb to the hill shifts back into overdrive and on down the road never dropping in the second gear for 4L80E is the way to go

[@teaguegearhart9851]

Loved the music on the work sections. Also this thing looks so much better. More of a power stance for sure. Very nice. Looks like that old axle has seen it’s day any how.

[@schwanzmunster2503]

That is a very nice looking Suburban. Much better body style than the new ones. My dad had a 1999 OBS K3500 with that track width issue. Couldn't back up a trailer straight. I am a huge 92-96 Bronco Fan. Best Ford body style.

[@cool62chev]

Wow, what a difference! Love it, definitely not crazy to do it.

[@austinandannah5357]

The rear axle is narrower for a performance reason I guess you could say. When you’re driving through snow or sand having the rear wheels narrower helps the vehicle track straight. When the front and rear have the same track width the truck tends to float and move left to right.

[@jr78racer]

Looking good. Rear stability should be improved by the swap as well. Should make it an even better tow rig, if that's what you're after.

[@YouTuber1g]

Really love this channel, LT. Greetings from NJ. I have an 03 Dakota Full Cab 4.7 Magnum w/ 127k, and a 04 Grand Cherokee WJ 4.0 w/ 207k. I'm fortunately the second owner of both as well.

Awesome stuff LT!!! On our 99K2500 we run a 35/12.5/20 Toyo MT setup on a 4x 20x10 aluminum wheel, with a 3” spacer on each side with dual air ride 1 ton bags rear to match the Torsion bar cranked RCD 6” lift on Billsteins 5100s, with the oem the Z85 Towing package Axle with LSD. Love your Fabrication bro👍🏽🔥🔥⚙️⚙️

[@hunterbrock2347]

I'm looking at rear axle swap options for my 1995 Ford F-250. Achieving closer to similar width as the front would be nice but having the addition of disc brakes all around would make it worth while for me. I would be adding an automatic locker with the replacement axle out and being prepped anyways. I'm mostly likely going to use a GM axle since later Fords switched their bolt pattern to 8x170 instead of 8x6.5. A van 14 bolt may be my best option as it's 70" WMS to WMS and the Ford front end is a hair over 69¼". This series on the axle swap had been helpful in showing me what amount of work I have to look forward to so please keep it up!

[@idriwzrd]

The disc brakes and locker are worth the effort. The extra width is a bonus. Nice work, LT. Looks much better. Now, tell us how much better it wheels.

[@texaspoontappa8946]

Badass keep up the good work ol boy

[@2000S10V6]

Looks great!

[@Vaino_Hotti]

I just did a remedy for a similar problem on my '85 Grand Marquis. On it the rear track width is narrower than front, and the rear wheels are similarly sunken in the wheelwells. Though I just did spacers, since it cheap and easy.

[@joshuastanden]

The mountain of garbage left on the floor after dropping the old axle... lol.

LT, I always enjoy your content. For saftey's sake chock the front tires when you are lifting and placing a vehicle on Jackstands.

[@brickcasper]

On a level slab, why?

[@gben7084]

@@brickcasper cause cars slip off JACKS !!!!! and LT's kid is TOO cute to lose his Dad

[@shadowopsairman1583]

You mean using a jack...

[@brickcasper]

I still disagree. If a vehicle slips off a jack on the way up or the way down the front wheels being chocked won’t make any difference. If fact the jack wheels rolling or the vehicle wheels rolling are what prevent the vehicle from sliding off the jack pad. If the vehicle wheels are chocked and there is any debris on the concrete and the jack doesn’t want to roll and then you have an issue.

[@MonygyB]

I’m jealous! I just bought a ‘93 k2500 pickup with the 6.5l diesel! I noticed the thinner track width in the back and was somewhat distraught, but I’m too happy with the truck to car lol

[@brickcasper]

LT, for the look I think you did a great job, mechanically as well you nailed it. BUT I can’t go along with the axle choice. Picking a somewhat obscure diff would be a deal breaker for me. It just so happens that I just wrapped up an E-locker install on this same D70S. I ran unto a post on pirate4x4 that gave me a little heads up about axle lengths because of the side gear locations on the regular D70 vs this D70s. It was helpful and you may want to research it if you plan on ever doing an upgrade from the factory LSD.

[@LawrenceTolman]

I'll have to check it out! got a link?

Because I've owned 2 that have been my daily I never really thought about it but this is absolutely looks so much better.. Can't wait to see the driving and new master.. One day I might just do this myself.. Until then I have some suspension maintenance and injectors to replace.. Oh and a little exhaust work.

[@80sfordguy]

Awesome job LT, nothing better than a stock upgrade of LSD with disc brakes as well not to mention also widening the track width all at the same time. Personally, I can’t stand it when a mild upgrade is completely captain obvious due to its mounting or visible location when stock appearance is the goal. Upgrading while keeping a stock appearance is always a labor of love vs performance and a lot of times difficult to do on certain upgrades. Can’t wait to see what you do with the engine in later videos!!!

[@LawrenceTolman]

I totally agree. when you look at it now it just looks right, but unless you know these trucks inside and out, you would never be able to tell that its not the stock width
