I have a stock '89 suburban, 4x4, 1500, auto that I picked up this weekend. It has a slight shake in the wheel that seems like a combination of a warped rotor(s) and soft brake hose(s). The kicker is when going over a road paved road with many shallow potholes the front end suddenly starts oscillating left and right nearly uncontollably until i swerve left or right loading everything to one side....this acts similar to "death wobble" typically seen more with large tires and suspensions. I just got it and haven't had a chance to crawl under it and see what's up. If anyone has encountered something similar. please give me a shout.

Thanks

Welcome to the site :sign0016:

I suspect the sway bar, but I never had something like that. Yellow Hand Line Finger Thumb

Ditto, check the shocks and other suspension items like tie rod ends, and control arm bushings.

A full front end inspect would be in order. Sway bar to wheel bears and everything in between. Keep the trips short until you get it done. It doesn't sound very safe. Cuz' spilling your coffee in a roll over is not cool. :gasp:

I hate when that happens! Been upside down twice, and I can laugh now but it wasn't very funny when it happened.

Check/replace the tie-rod ends, but 8/10 times a good alignment and tire balance will fix it.

Whatever you do, don't try to hide it by getting a new steering stabilizer!

Also take a look at the idler arms grab them at the ends any up and down motion they are shot! That will cause one hell of a wiggle!

These guys are all right, because when something similar happened to me I did everything that they have suggested to you in this thread. None of what they have suggested to you worked for me. I ended up listening to my girlfriend (I should have done that from the beginning) and I bought a new set of tires. It ended up being sidewall problems on the insides of my tires, and now I have no problems at all.

Sounds like you had a defective tire, that should have been caught when they balanced them.

Or you didn’t have truck tires, some people will put car tires on before they sell their truck so it looks like you have good tires. But the sidewalls are thinner, less plys.

Always but tires rated for trucks.

Oh ya Jaymack and from the looks of your picture of your truck you need a ball joint.

LOL Nope, no ball joints needed. Thats what most people say when they see my suburban. I have a complete custom made air ride system and when its layed all the way out they camber in like that.

About those tires, they were rated for a truck, and they didn't develop the sidewall tumors until a year after I had gotten them. It was just a freak thing I reckon.

Well now I understand why your sidewalls were bad. There is no way any tire can handle the things you did.

Doing things like that to a truck cause problems and not just to the tires. What happened to your truck is not related to the problem someone would have with a stock truck, In this thread.

I’m sure you will have the same problem with those front tires again if you continue to run like that.

Normally I don't drive it low. I have my wheels aligned at a certain air pressure and I keep it there. When I am displayed or parked, I lower it and all the weight of the truck is no longer on the wheels, but on the frame instead.

It still doesn’t do the tires any good, driving or parked.

I could correct it by putting on drop spindles, but its an attention getter at the shows, and people seem to like it. They ask questions if they are confused about it and I enjoy talking to them about it. It helps folks that don't understand the mechanics of air bags to see it operate and then they catch on a little better. Plus, almost no one has negative camber like I do...
