Hi there I had a strong vibration on steering wheel when i braking and I replaced the front brake discs. The vibration of the steering wheel is gone but the vibration on the body still was, then I replaced the rear discs but the problem did not go away. I took off all the disks and cleaned the hubs I thought that there was rust and the disk was crooked but the problem remained. In what a problem? crooked hub?
I'd also inspect balljoints as well as the aforementioned mounts. How long was the car sitting? Possibility as well the tires are either flat-spotted, or maybe in need of balancing.
Here's a recent thread regarding vibration. Doesn't look good. I hope this is not your case. https://www.ferrarichat.com/forum/threads/360-engine-trouble-maybe-crankshaft.583415/
I thought about it and removed the brake discs and did not see the problems at the hub from the bolts
So here is a stupid idea. Have you checked the wheel mounting surfaces to make sure that they are all smooth and clean? IF you have something stuck in the wheel or hub it will make the wheel slightly out of true to the rotation and it would feel like a balance issue. Well, kind of. It would actually wobble but it would probably feel like balance.
If your issue is only under braking, and it is causing pulsating, then I would verify your rotors are indeed flat. If you overtorqued your wheels after the new rotors, it can cause them to warp (ask me how I know this). I would also check to ensure the caliper bolts are tight as well and verify the pads are installed correctly.
Something wrong Wheel bearings Install error Pad transfer Rotor warp Bad shock Bad bushings Steering rack Wheel balance (force balance) Bent wheel ABS Bad tire
This is a link to bed in disks Cant hurt to try .. no downside https://brakeperformance.com/bedding-in-rotors.php Sent from my moto x4 using Tapatalk
As I suggested ..rebedding will eliminate that issue .. follow the link that I posted above Sent from my moto x4 using Tapatalk
