2002 F50 Steering wheel 'shake'?????? (also need advice on 22"s)

Kev1n,

Did you have vibration during braking, or simply while driving. I feel no pulsation when braking, only when cruising between 50 and 70. Still trying to understand if/how bad rotors cause a vibration when cruising but not when applying the brakes.

Sorry to

I just don't want to spend any unnecessary money replacing parts that aren't in need of repair.

phatyak,

initially i had vibrations during both braking and cruising. I did the brakes first it it got rid of most of the vib except for the one around 80mph. I had the oem tires/rims balanced and rotated, it mitigated the vibration, but did not eliminate it completely. After the new rims/tires its all gone. I would definately reccemend new rotors for you to get a clean slate.

Kev1n,

Thank you for your input. I agree, replacing the rotors can't hurt anything and it would give me a baseline.

I think I will have the wheels road force balanced first. If that doesn't help, then I will replace the rotors. I know I will have to replace the shocks/struts and the tie rod ends sometime in the next year or so as well. If all of that fails, I will look into the new rims. Those 19's look great, but that is an expense I am not sure I am ready to incur any time soon (baby on the way).

Thanks again.

WEILL I JUST PUT 22'SON MY Q45 IT WAS 235/30/22 WITH A 35 OFFSET AND A 8.5 BOLT PATTERN SHE LOOKS MEAN AS A PITT BULL THE S550'S LOOK AND ASK WHAT IS IT SHE LOOKS GOOD.. SO HIT ME BACK IF YOU HAVE ANY ?? MY BOY HAS ON HIS Q 245 /40/22 WITH A 35 OFFSET ON 9.5 THE WHEEL PLACE SAY IT WONT FITT BUT IT WILL CAUSE HE IS RIDING ON THEM SO THERE YOU GO.

Sorry for the late reply.

My car only shook b/w 68-73mph and it shook bad enough to annoy me. Beyond 80 it was not much, below 60 it was slightly there.

There was no pulsation on braking b/c All 4 rotors/pads were brand new. I can stand on the brake and there would be no vibration.

I think the rotors were not balanced.

But Guys here's the key thing...

I would get my tires balanced from Discount tire direct, Everything would come out to 0.00 .. Take 1 sping down the hwy and it would be great for about 5mins and then it would start shaking again.. Come back put the tires back on the balancer and All 4 tires were out of balance. This really bugged me. So BF GOODRICH replaced all 4 of my tires with Higher load rating tire and that Fixed it slightly but not by much.

I told them maybe the rim was spinning on the tire. They said I was crazy..

Crazy or not, I had an expensive car and didn't nead a headache of getting tires balanced 2-3 times a week.

Any update on this? I'm having the same problem.

[Q45tech]

Start out with having all 4 tires road force variations measurements should not exceed 10 pounds and final balance should be trimmed to less than 3 grams inside and out even if you must cut 5 gram weights to fine tune.

I always test my wheels when swapping tires if the wheels are more than 5 grams out of balance without tires, I fix that first before mounting new tires. THERE ARE special metal pads in quality wheels where you grind off metal to balance wheels.

So you KNOW the level of precision I am using a post 1982 US penny weighs 2.5 grams.

Vibration free driving demands perfect road surfaces and a level of precision most don't get anywhere near and even that goes away with a pothole.

Try to have a Road Force Balance on your car, it is worth every penny. If you have not done that yet,
