So my ailment guys said some of my issue with a pull may be a crab walk the right rear is more curb than the right front.

What’s the fix? is this a welding issue trailing arms any ideas?

you need to get a 4 wheel alignment check to be sure what is off.

As you may already know, a crab walk alignment is caused by the drive axle being out square to the chassis. I would find a reputable truck repair facility to investigate. Could be failed welds at the axle attachment points, badly worn trailing arm bushings, a failed trailing arm mounting arm to name a few. A thorough inspection should pretty quickly find the cause

If anywhere near Florida, Barry at Josam's can take care of it.

One of talented members had his out 3/4" from factory . He made one or both trailing arm adjustable.
The bushings and or egged out bushing bolt holes more likely or cracked welds. A inspection for cracked welds is needed right away.

Had inspection for crack welds none found.

Have a feeling it been this way from the factory and the fix may be costly.

My understanding is the rear would need to be cut and welded.

I am in AZ and I don’t think there’s a good shop like Henderson or Jonas here.

Would be a good place to open one I would think with all the RV traffic in AZ.

Phoenix area but would travel some distance was planning a trip to source engineering and Henderson straight line at one point but was waylaid in another direction.

May get up there latter this year if I can’t find another option.

The rear definitely would NOT need to be cut and welded. Whoever told you that is not qualified. If all welds are good then the trailing arms or their mount location is the cause and can be corrected by altering the length of a trailing arm or replacing it with one the can be adjusted.
If the same shop that told you the welds would have to be cut is the same one that told you all of the welds were good I wouldn’t trust their inspection and would find another good shop to inspect it.

Good luck!

I think you just confirmed what he said

You have to cut and weld. I have wondered if some of the heavy duty trailing arms that are adjustable could be used.

Mike Z (ZMotorsports) is a very talented IRV2 member and You Tube poster. He has a 2003 Dynasty that the rear axle was not inline with the front. He posted a very detailed You Tube video on how to correct it as well as a thread on IRV2. He has been posting for many years so you'll need to search through his very long thread or search his You Tube videos.

I guess I did.

. I was referring to the fact that he was told that the axle would have to be cut free and re-welded. I would be going down the adjustable path for sure.

Biljol · 01-19-2022, 07:05 PM

Yes I saw MikeZ video and that’s what I was referring to the need to cut and weld the trailing arms/make them adjustable.

Note my 2000 exec is a tag so that process is I think a bit harder that a single rear.
