Andall they needed to do to prevent all this spending money on parts and labor was squirt a bit of grease in ‘em every once in a while. Price of being LAZY…..EXPENSIVE!!!! (I didn’t hear you say anything about THAT!! You should’ve said that right when you discovered the bind. That all they needed to do was give the dang thing a shot oe two of grease once in a while and they could’ve prevented this whole mess, but it’s to your benefit to get their business I guess, eh?? Hmmpf.

[@georgeweisbrod1876]

You got it apart. Makes no sense to do it all to both sides. But then you look at owners lack of easy regular maintenance they will only let Ray do the least work then complain when another should have been replaced part fails.

Yep I'd have seen the spacers and the ghetto lights and told the kid to come get his truck. Jeez !!

[@Wakeupandsniffthecoffee]

Back in high school on Maui in Hawaii, we all drove some sort of 40's and 50's military jeeps. We had locking hubs that were tough to change the position on. Later out jeep wagoneers and other trucks also had. The death of them was changing the position from lock to unlocked and forgetting the other side. Then driving across the island with one wheel hub locked. Great way to burn up the hub or universal. They didn't have no fancy light to tell us if they were in either position.

[@gunlover1955]

Just think a little grease over the years and that part would probably still be good. Great call Ray!

[@burtzorn4059]

My 2001 Super Duty had greasless ball joints. Took plugs out put zerks in and greased them . Took care of my catch problem in the stearing . Life time grease ran out at 50,000 miles lol 😆 We ended up putting zerks in everything we could. Huge difference in the handling.

The 'Carolina Squat' is illegal in North and South Carolina, and Virginia. It didn't even originate in the Carolinas. It's from California and from Baja racers. It looks like a dog dragging it's itchy sphincter on the carpet and screws up suspension geometry. This truck had all the poser toys.😂

[@laurence1643]

I had the exact same problem on my 97 f350. We replaced the axle u-joints and the inner seals in the differential. We had it all apart, putting in a Eaton true-trac. The original u-joints had no grease fittings and were dry causing the needle bearings to rust. I was really glad to get it all fixed and not get stranded offroad. Long-time fan. Thanks Ray .

There’s nothing quite like the sound of a bellowing big block. I was somewhat lucky to have experienced a Chevy 350 in a boat with no muffler, no catalytic, just a straight pipe. On weekends we could wake up the whole postcode with that baby.

[@oobaka1967]

Concerning any flex or tilting of the lift....you could always get a digital angle finder. They're magnetic and measure in 10ths of a degree. Put it on the lift, zero it out and then, if the lift tilts even the slightest, it'll show up. They cost less than $40

[@oldtimefarmboy617]

I was a truck mechanic decades ago. I worked for an oil well drilling company and the two managers had Chevy suburbans with 4-wheel drive. The steering axle used a double u-joint assembly on each wheel and those u-joints would go out every few months. Royal pain in the rear to fix. Nothing was easy about taking it apart, replacing the u-joints, or reassembling it. And they never wanted to replace the other one at the same time because they were too busy. So when one went out you new you would have it back in a few weeks later to do the other side. And they were busy busy busy, hurry it up, what is taking so long.

[@chriskline3763]

I took an alignment class from Hunter. The instructor said that the F-250/350 came with factory Death Wobble.. We all laughed had a good time....he then showed us the recalls and probable causes of Death Wobble. One of them from Ford was that if said truck was lifted to remove lifted parts and return to factory spec, another was to make the caster more negative. I thought it was a neat thing to learn. That's also why I watch Ray to learn other methods of fixing problems.. Thanks Ray.

[@AT-wl9yq]

Hunter is a marketing company. They give you their version of what an alignment. He was right about removing the aftermarket parts, but with a solid front axl, you can't adjust caster/SAI. Also, if it was adjustable, you would need to make caster more positive, not negative. That's why its prone to death wobbles in the first place. A solid front axl forces your front end geometry to be less than optimal. Its a sacrifice made to increase durability.

[@redmondjp]

I think you meant to say, make the caster more positive. I need to get the aftermarket eccentric cones (that install on the ball joints) for my 2005 F350 4x4 front end so I can increase the caster angle. No death wobble but it tends to wander and not return to center as much as it should.

Exact same problem with my 14 F250. A Shop swore that couldn’t be the problem. I put the truck on a lift myself and there it was. Scared me a few times straightening out of a corner and the wheel didn’t want to come back to center.

[@1crustyoldmsgtretired870]

In regards to the heavier socket, you're correct. Because K= 1/2MV^2. The more mass or velocity, the more kinetic energy available. Having phun with physics

[@aresler6085]

Well done finding this odd problem: it's not obvious. An 88 F250 I used to own had the exact same issue. As I recall, I had to disassemble the wheel bearing to get to the nuts holding the spindle to the knuckle, which, this being in New England, was properly rusted in place. I had to jack the spindle out with a ad hoc screw jack between one of the spindle studs and the wheel bearing nut. But it fixed the steering problem when all was done.

Wow, when you were trying to turn the wheel I could have swore I saw that right side universal jump, it binded just as you put pressure on the wheel just to turn it

[@cliffyb5896]

Being from the rust belt, I would have went straight for those u-joints.

[@Mr572u]

Great catch! I’m thinking that truck never gets put in four wheel drive. With the hub unlocked and the transfer case in neutral, nothing spins. The axle and u- joint find their happy place and stay there, causing the u- joint to seize. I think running in four wheel drive every once in a while is a must!

[@JM-lk6wo]

Judging by the appearance and cleanliness of the truck, I think the poseur owner never gets further 'off road' than a gravel parking lot. This in spite of the thousands he has spent on his manly posturing.

[@stevepreskitt283]

Or just don't buy a 4WD vehicle if you don't actually need the extra traction. A 2WD truck will be able to haul/pull more on dry pavement, is cheaper, and there are fewer parts to fail. Two thumbs up for Ray's diagnostic skills and attention to detail!

[@mxpants4884]

​@@stevepreskitt283Why will a 2WD be able to haul more? Just the reduced weight?

[@stevepreskitt283]

@@mxpants4884 Reduced weight and reduced friction in the front end by eliminating the transfer case, front diff, axles/U-joints, etc. If you look at the specs on comparable 2WD/4WD models, the 2WDs will pretty much always have a higher cargo/trailering capacity.

As I live and work in a salt belt Ray you are blessed with so little rust. Up here I guarantee that would have been a major battle to disassemble. What I find concerning as well is the amount of metal chunkies in the splines around the snap ring at 36:00 minutes into the video. More damage in there besides the u joint.

That ford 4x4 vacuum seal is a replacement every time it’s taken apart and has a special tool to reinstall it. Done many of them. Supposed to smoke test the seal afterwards to make sure it doesn’t leak vacuum. Kit from ford comes with new o rings on the bearings and a new cover gasket. Be sure to replace them all.

[@buddyphillips9790]

Probably locked up from lack of maintenance. Those u joints have a grease fitting and you have to grease them periodically... Homeboy was too busy installing wheel spacers and 22s and didn't bother to grease his truck lol

[@pks2634]

At 23:28 you are trying to rotate the wheel and universal joint on the passenger side. It looks to me like not only is that universal joint having a problem but so is the axle bearing. It really looks to me like that yoke on the axle is moving up and down back and forth also.

[@richardstone5241]

I used to build off-road rigs in Utah from mild to wild rock crawlers. Pay close attention to the geometry of ANY lifted vehicle because almost ALL lift kits get it WRONG. Instead of engineering their kits properly they choose to push the stock limits to the point of being DANGEROUS. Why do they do this?................To keep the cost down to the consumer who does NOT want to pay the bucks to do it right! I know lift kits, big tires and wheels look cool but you are asking for trouble and more often than not your rig will actually LOOSE off-road performance. My advice? Learn how to drive off-road, know the limits of your rig and if you want it to perform like a rock crawler, build one. BTW Ray, be sure to check that Track Bar really good because 90% of the time it will be faulty and a root cause of Death Wobble. One last thing guys, DO NOT USE WHEEL SPACERS the stress they cause on bearings is unreal.

[@TheRealSlowhand]

Great video... Most people don't realize they have grease points all through their front steering/axel assembly, ARod has a video about that though... Be careful with the inner axel seal when you reinsert that axel shaft... I was not as careful as I thought I was and ruptured mine... Of course, you don't find out until days after full reassembly when you get the wet spot out the end of the barrel and then have to completely disassemble again... As well as remove the diff cover and gears to get at those inner seals...

[@acdii]

Thats a dry seal. If you get lube coming out of that one your inner seal is bad. Go back and look at the tube in his video, you will see it is dry to the pumpkin. The axle seal is to keep moisture out, not lube in. The BIG seal on the axle requires a special tool and is a PITA to install too. I've done a few of these front end repairs.

[@TheRealSlowhand]

@@acdii I said nothing about the dry tube or any other seals... I specifically said the "INNER" axel seals... You know, the ones that require the removal of the diff cover, and ring gears to get at the seals... I don't think you read my comment completely, or you didn't understand my comment...

@@TheRealSlowhand Ah, sorry, misread it. I was looking at the end seal as the inner seal, and the big one in the hub as the outer seal. Totally missed Axle in what you said.

Not sure why it’s so common for Superduty owners and lube shops to miss the front you ujoints. All Superdutys with the Dana 60 or Super 60’s have serviceable front ujoints. They are the only grease fittings on the truck. Make a habit of hitting them with a couple pumps of grease at least twice a year, or more if you use four wheel drive often.
