Rear wheels try to move further apart from each other while driving forward

[Migri]

Hi. I'm new here and I'm from Slovakia, so my English is supplemented by a translator.I would be very happy if you could help me, I haven't found a thread with the same problem here.

I bought my first Jeep LJ from 2005, which was not drivable, so I don't know how the car behaved before the total reconstruction. I lifted the chassis by 2", all the arms are new original parts. I have a problem with the rear axle, when driving forward from very low speed the wheels try to move further apart, when reversing they want to move further apart.

I have Dana 44 .

Sorry for my picture, I can't explain it better, but this is the direction the wheels would like to go.

thank you all for your help

Missing C clips in the differential?

Although I thought a 44 didn't have c clips.

thank you for responding. I don't know exactly what you mean... but when I changed the bearing, I pulled the axle shaft out without having to open the differential, so there may be something wrong there

I was thinking the same thing until I saw it was a dana 44 .

I know what you're talking about, but I didn't pull out any c clips, and I also read that the Dana 44 doesn't have them. But before I changed the bearing, the axle shaft went in and out as if the c clip was missing.but after the replacement it got better.Just to be sure, is it a Dana 44?

 

[tr21triton]

yes that's a dana 44.

Could something be broken inside the differential and that's why the axle shaft is moving?

I've heard that the axle could be faulty.

I can't think what would cause both tires to move that way in a solid axle. Maybe @mrblaine has a idea what might cause this.

Outer bearing retainer plate then...

Any chance you forgot the bolts or the backing plate that retains the outer bearing?

Only other thing I can think of is a wallowed out or loose connection where the axle tube is pressed into the pumpkin. On the pic, it looks pretty solid on the drivers side, but can't tell what it looks like on the passenger side.

Before I get too involved, I would like to know what is being seen that makes it appear that the tires are pulling the axles out of the housing.

Does Slovakia have camels?

no the board is tight and solid

the right side is also solid, it has no movement in the bearing. the picture should be taken with a grain of salt, let's assume that both wheels have the same camber, of course it's not as visible as in the picture

you can see that the wheels turn to a certain point, where they stay until I start reversing, then they turn in exactly the opposite direction. when driving faster through the zebra crossing (white lines) the tires squeal

only ZOO

I just realized something that might be related.

I replaced the entire suspension with new OEM control arms, lifted the vehicle by 2”, installed Bilstein shocks and springs, and kept the rear OEM panhard bar with a 2” lift reducer.

However, the key point is that I installed everything on the chassis without the body and engine, so the vehicle was not under its normal weight.

After installing the body and engine, the car was properly loaded.

Could this have caused the control arm bushings to be preloaded or stressed, affecting the rear suspension geometry?

So far, that is an accurate description of what you see when you go forward and then reverse. The squeal on the white paint used on crosswalks is also normal, especially if they are slightly wet.

I suspect we need some manner of a digital movie showing the problem.

Yes, but the only consequence of that is premature bushing wear.
