Suspension issue? - Toyota GR86, 86, FR-S and Subaru BRZ Forum & Owners Community

Dacfrs · 11-26-2017, 01:44 AM

Okay, going down the interstate, truck blows tire, pipe falls off truck into road, I manage to get my FRS down to about 65mph, before I got no where else to go, and run over the pipe. Both driver side tires blow out, I pull over, call AAA, get new tires and continue my trip. Only now, something is not quite right, traction control comes on in corners now where it did not before. Car feels loose, basically as if the entire rear end is loosely mounted, feels like it wants to swap ends. Toyota dealer says they see nothing wrong, technician drove the car said he didn't notice anything odd, but I believe he doesn't know the capabilities of the car, so I don't think he put it through it's paces, so to speak... New tires were installed on the front...I've swapped them around, same thing. Struts appear to be ok, no leaks, no funny noises. Any suggestions?

I'd suggest you take your car into a good alignment shop for an alignment and a complete suspension inspection.

Are the new tires installed one on the front and one on the rear? If so then that's your issue.

I would put the new pair of tires on the rear and the old set up front.

Strange as it seems but out LSD does not take to kindly for one new tire and one old.

Welp, Mr .ac , you're getten it more right.

I suggest you ditch those readers you got off the rack at Walmart and get some good ones off the rack at Walgreens.

Rear wanting to swap ends means when it wasnt doing it before means you have toe-out on 1 of the rear tires. I tapped a wall while doing a time attack event with my rear driver side rim and it got me an instant -0.25 toe there when there was 0 before. The car was soo loose at turn in after that. Like everyone else said, take it to an alignment shop and it should be a quick fix. Toe in the rear is just an excentric bolt so it can slip out of position without a big hit.

Any luck on finding a solution? I have had a similar "loose" feeling recently develop.
