High speed vibration

Thomaszhuu · 05-20-2023, 10:51 AM

I’ve noticed a bit of grease around the heat shied where the u-joint sits at. It’s currently on te37sl with Firehawk indy 500. It gets better when I brake and decrease speed.
I agree -2.9 is a bit aggressive for street driving but not sure if it’s due to the ride height of the car, but I’m maxed out on threads for positive camber.

When did the vibration/shaking first appear? Did it appear following one of your suspension upgrades? You may be able to isolate the source if you retrace the timing of the upgrades to the beginning of the vibration.

Hard to isolate the source since I did all of the suspension upgrade at once, I noticed the vibration/shaking concern last summer. I don't have a way of swapping parts since I sold most of my stock components..

So not to say the obvious but were the wheel mating surfaces to the wheel hub properly cleaned? Then were the wheels properly torqued in a star pattern with the proper bolts for the new wheels? Just a thought.
