Check for cracks on the diff, and your driveshaft..

 

do these things just break or is it a wear and tear item. What should I be looking for

 

The driveshaft vibrates w/ higher speeds, the mounts cracks on the rubber.

Next time you get an oil change from the dealers, ask then to check all the mounts for you, engine, tranny, and diffy. Its freet o inspect if you do an OIL CHANGE

If you just bring it in, its a 60.00 diagnostic check.

 

Sounds like it could be your tires tracking the rain grooves in the freeway.

Try driving at the same speed on an asphalt road (no rain grooves) and see if it does the same thing.

If that's the case, there's really not much you can do about it.

 

Post in the South Florida forum...get Firestryke (Alex) to drive your car and let him tell you if there is a problem.

 

i made a post a few days earlier about the same problem. still haven't figured out what could be causing it, but it started after i put on new rear tires. toyo 245/45/16. It feels very unstable at highway speeds. I think this car is really picky with tires.

 

So you'd put a 100,000 mile tread warrantied tire on your car? Of course not, but some idiot at the tire store might care more about a sale, than special ordering the right set of tires.

I did say OEM or better. But OEM will at least be stable and safe. That was my point. I wasn't trying to sell tires or anything.

 

What about the sway bar end links, maybe broken or loose?
