Hopefully someone can give some insight on this, I have read through the other forum posts but have not found anything specific that might help, so I thought I would ask. 96 Tahoe, has an annoying bounce that feels like it's coming from the rear driver side of the vehicle, it had a questionable tire on there so I decided that I would get a new one. In the process I found a nice set of used wheels that I wanted to put on also. Ended up purchasing 3 new tires (one original tire was almost new so I didn't replace that one) to put on the wheels, all were mounted and balanced and put on the vehicle. The vehicle now along with the annoying bounce in the rear end, now has a squirrely feeling when driving over the back roads near our house and will sometimes shake uncontrollably and you have to slow down to almost a stop to get it to straighten out. This vehicle had no front end shake before the new tires and wheels were installed today. I didn't think these tires were that much larger than the original tires and was in hopes of avoiding this shake. I have a 94 suburban that has this same exact problem after installing a set of aftermarket wheels and fairly large tires, we replaced almost everything under the front end of the suburban and nothing ever took the shake out of the front end and we have been driving it like this for over a year with no problems and no unusual tire wear, so I don't want to go through the whole process of changing all the front end parts on the tahoe just to find that it does no good. Is there something I am missing? I know the control arm bushing were one of the things that were not changed on the suburban, I just didn't think they could make that much difference. Both the suburban and the tahoe appear to need them. Can this be a source of this whole problem I am dealing with on these two vehicles and why would I only experience the shake after installing aftermarket wheels and new tires? And if the bushings were bad shouldn't it have the same shake if the bushing were bad with the factory wheels? Any help would be appreciated. Thanks! The tires are 265/75/16 on american racing rims.
