Rear end feels loose. Need some help....

Hello, I am new to the forum and need some help. I have an 05 Tib GT. The rear end sways back and forth in snow and skips side to side going over bumps. Rear end just always feels very loose. I had the sway bar bushings replaced under warranty at the dealership about 1 year ago. I am assuming it is the same problem again. Anyone else experience this problem with a different solution or know what may be causing these bushings to go out consistently? I purchased the car new and unfortunately have had nothing but problems with it. Thanks in advance.

Maybe the rear-end is out of alignment. A premium 4-wheel alignment may do the trick.. I've dealt with this problem on other vehicles(including my own!).

Well that is the funny thing too. I had that done last winter too. Hasn't even been 15,000 miles since I had it done.

An alignment can be knocked out by many things, and a Tiburon is well.. weak. Pot holes, animals, and other things can knock out the alignment. Installing new bushings will skew alignment, also. What size tires are you running?
