'98 GTP w/160k miles... the one in my sig and I'm debating on selling it or keeping it. I just want your guys assessment on this before I make a decision.
I got this car as a total mystery and it had some abuse. It has had right side damage at some point, maybe twice. Once was rather superficial and ripped the sideview mirror off and did some rear quarter damage. The one appears to have bent front control arm mounting point a bit so it's not totally square and the car does have excessive camber on the right front wheel that will have to be dialed out. That said, I don't see anything rubbing or that would cause this.
Symptoms: Car moves and accelerates fine. Grinding noise is heard from the right front at low speeds. As speeds increase to 40mph it becomes a tremendous vibration that jars the whole car, to the point I've driven it less than a mile while testing.
Items replaced:
-Control Arm w/ ball joint.
-Strut and strut mount.
-Wheel and tire (rim from my good GP with brand new tire to see if that helped).
-CV Axle
-Hub/Bearing Assembly
-Pads/Rotors
I'm assuming its the differential blown from somebody playing with burnouts or maybe from the impact. Can a blown differential cause such vibration on the passenger side only, yet still propel the car forward like normal? I have jacked the car up, put it in drive and let the wheels free spin. The same grinding/vibration comes from the right front and increases with speed, and I have no idea exactly where from. I have felt around the tire and even with the camber issue it isn't rubbing any components.
Throw some guess my way.
