Zip Tie Posted March 13, 2020 Share Posted March 13, 2020 I need help with my rear wheel alignment on my 91 4wd loyale. I've taken it to 3 different shops that couldn't figure it out. First shop said it couldn't be done. Next shop pushed it way out, so it looked like an old vw bug, then couldn't figure out how to get it back in. The third shop was able to get it close to where it need to be (see pic) but not all the way. I found a page from the FSM that explains it, but I was wondering if there are any tips/tricks I can tell them? Quote Link to comment Share on other sites More sharing options...
DaveT Posted March 13, 2020 Share Posted March 13, 2020 I had a thread / post about this, and a rig to DIY. The only adjustment is the 3 bolts on the trailing arm. Quote Link to comment Share on other sites More sharing options...

If you look at my tire it looks just like the wear from a camber issue. How would i fix a camber angle problem? Quote Link to comment Share on other sites More sharing options...
DaveT Posted March 14, 2020 Share Posted March 14, 2020 The ride height might mess with that some. In your pic of the wheel, it looks like it's leaning in at the top, that's opposite of where mine are, unless I have a really heavy load of stuff in the back. [I have mine set on the highest notch on the rear shocks] Worth checking the bushings too. The big tube that all the rear suspension bolts to - make sure it's not rotted out. 1 Quote Link to comment Share on other sites More sharing options...
Crazyeights Posted March 14, 2020 Share Posted March 14, 2020 Some people pay crazy money for camber mods like that 1 Quote Link to comment Share on other sites More sharing options...

It does tilt in at the top. When I first got it the rear wheels didn't stick out like this at all. The first shop said they were a little out of alignment but they couldn't be adjusted. The second shop pulled the drivers side tire way out (so it looked like an old vw bug) then told me they couldn't figure out how to get it back in. The third shop was able to pull it back in a bit, but not enough. What are they not doing? I can't have this thing eat tires like this.

el_freddo Posted March 14, 2020 Share Posted March 14, 2020 I can tell you what they ARE doing: loosening the three bolts on the outer swing arm to make adjustments. These three bolts are set from factory or the dealer as part of the final inspection and are deemed “unadjustable”. You need a shop that can look at toe, camber and castor as one setting - those three bolts do all of that for the rear end - it all depends on how they move the hub part of the swing arm in relation to the front section of the swing arm with the three bolts. Tiny movement/changes at the two halves of the outer swing arm make big changes at the top, bottom, front and rear of the tyre. It’s not an easy adjustment to get right - and access to those bolts is limited. Cheers Bennie 1 1 Quote Link to comment Share on other sites More sharing options...
DaveT Posted March 15, 2020 Share Posted March 15, 2020 My 86 FSM shows the toe and camber adjustments using the 3 bolts. They do interact. I got lucky when I corrected the toe on mine, didn't have to fight with a bunch of interaction. Yes, they don't move much, but apparently, they have a noticeable effect. With them as far out as you have, you don't have much to loose trying to adjust them. They are a pain, you have to pull the tire off to really get at them. At least get the bolts freed and anti siezed , then start trying to get the angles set. I can try to scan the page tomorrow. Quote Link to comment Share on other sites More sharing options...
Steptoe Posted March 15, 2020 Share Posted March 15, 2020 It does my head I trying picture how these three bolts can impact the alignment , toe and caster of the rear wheels Quote Link to comment Share on other sites More sharing options...
el_freddo Posted March 15, 2020 Share Posted March 15, 2020 The bolts are in a larger hole and the thickness of the bolt thread. So the hub can effectively move closer to, or away from the swing arm mount a few mm. And by raising the bolts relative to their holes, it twists/rotated the hub face so the tyre can have loads of positive or negative camber. I hope this helps Jono!
