Growling Right Wheel

[Chalkmonkey]

I've got something going on with the the RH strut or the tie rod end or the rack and pinion. It won't make the noise when first driven, but after about 15 or 20 miles and everything gets warmed up that's when it begins. Can anybody give me a suggestion as to what may be causing the problem.

Does it make this sound constantly or only during turns. If it makes it constantly I'd be willing to bet it's your wheel bearings. If it's only during turns it could be air trapped inside the power steering lines or could be the bearings in the strut tower.

Give a little more info so we can help you more effectivly. Describe the noise also.

I set the front end up on jack stands yesterday. With the wheels off the ground you can grab the RH wheel and move it from left to right (which turns the steering wheel) and the growling noise occurs. The noise reminds me of a part that might be running dry, but I can't find it. Does the rack have any way to be greased.

Disconnect the tie rod end from the knuckle and repeat the test. That should help isolate the strut mounts from the rack.

Thanks,
I'll give it a shot and get back with you.

It might also be the upper strut mount rubbing against the inside of the strut tower. When the upper strut mount has been moved outboard to add positive (less negative) camber, the outer diameter of the rubber muont can rub against the metal tower and cause a groaning noise when the steering wheel is turned.

I use Sil-Glyde silicone grease in the interference area. I apply it to my rubber-gloved fingers and stick my hand up inside the tower when the wheel is turne full lock. The area of interference is usually the outboard area. Here is a photo of my driver side strut assembly after removal from the car. You can see the area of interference and wear at the near side of the top of the strut mount. Even with the spacer at teh top of the strut, the assmebly must be moved that far outboard to get the camber to -1 degree.
