Please define the "problems entirely" here.
Not being a goof but this is like someone saying I hear a faint rattle noise some place on my jeep. What is it.
I know, it's just hard to nail down any specific thing.
The thread I linked above is one of them, a flat spot on the tire thump from the rear when cold at low speed. Goes away when warm.
I believe Blaine describes it as running over a quarter and being able to tell whether it's heads or tails. Basically every tiny imperfection in the road seems amplified. And I'm in PA, our roads suck, lol. I can feel the same bumps in my '08 GC with 130k miles, but they're much more subdued. I know some of that is the different kind of vehicle, IFS, all that.
I sometimes have a rocking chair feeling, like the axles are fighting each other or something. That has gotten better as I've replaced suspension components, but it's still noticeable.
Randomly it will pull a bit under braking. Rear brakes have been replaced. But it's not how hard I brake that's the issue, it really feels random. Not a hard pull either, just enough to notice. I was wondering if some play in the control arm bushings could cause that. I've tested it on empty roads from like 50mph hard braking and letting go of the wheel. No problems. When I did the rear brakes I flushed all the lines too. Could be a sticky caliper but it's also not always the same direction. Sometimes it pulls left, sometimes right.
The one thing I did solve with the front track bar was a bit of death wobble at freeway speeds. But I still have vibration above 55mph. It comes and goes, but I have stock gearing so I don't think it's driveline. The frequency is more an out of balance tire kind of thing. I believe it's more prevalent, even trigger by, acceleration. Seems to calm down when cruising at a constant speed. In any case I start to notice it approaching 60mph. One theory I have is that it's the same rocking chair thing I feel at lower speeds, just sped up.
Basically I'm trying to decide what to replace next. The rear control arms that I removed were definitely old, but the bushings weren't in horrible condition. Some cracking, but no major deformation or tearing. If I replace the front control arms and not much changes I'm pretty much down to the axle level. Maybe driveshafts, but the angles I have right now are very slight. The rear is almost completely straight.
All of this has somewhat improved as I've swapped things out, but I feel like all I'm doing is masking the problem and I haven't found the root cause yet. And it's probably multiple problems not just one.
Rotating the tires to see if anything changes is a good call though, I'll try that.
