987.1 steering grinding

[drjdog]

Hi

I've been getting (for the past year or so) increasingly bad grinding noises when I turn the wheel, when I hold the lock there is no noise, just when turning.

Happens when moving or stationary.

Are there bearings in the steering rack or on the column that could produce this? The steering itself feels absolutely fine, I've had the top strut and wheel bearings replaced...

Anyone else had this?

Thanks

Suspect it might be a seized track rod end

It sounds much more inside the car than I suspect that would sound. Also strongly suspect I would feel something through the wheel with that.

I guess I'll have to drop it in somewhere to see what the professionals think.

Other suspect would be seized / knackered top mounts.

I had the same problem a few years ago. I can't remember the web site I found that had the solution, but a joint under a rubber boot had gone dry. The answer was to put a small hole in the boot, squirt it full of spray grease and then put a dab of super glue over the hole to seal it. It fixed it on mine and has been fine for a few years. It was accessible just by removing the front wheel, so take the wheel off and get someone to turn the steering while you listen. It should be obvious.

I had this problem and it comes from bottom the ball joint under the brake disk on the outside of the car. I tried spraying the general area with WD40 but this wont work that well as the creaking is actually coming from inside the rubber drying out, ( I think i caused a lot of this myself by blasting under the car with a jet washer, so try not to do this) You can replace these parts if you want to part with a lot of your coin............or do what i did which is jack the car up and put full lock on so you can get under one corner of the car and see the offending joint (the bottom one) now if you look you will see the rubber housing where the noise is coming from. Now bear in mind these are not buggered as the garage will tell you, but are only faulty as they are making the noise, they still work fine and are safe and will not fail an MOT as there is no play in them, they're just dried out. Get some spray grease (NOT WD40 This time, this is too thin) in a can with a straw, take a pin and prick a small hole in the rubber housing, put the straw thru the rubber and spray away, filling the ball joint with grease (or even better a syringe with grease in) When you pull the straw out clean the hole and put a small dot of glue on the hole (if you can see it that is) just to seal it. Do the same to the other side and job done, drop the car back on its feet take it for a spin and the creaking will stop as soon as the car has been bouced about a bit to get the grease in the right places. I did this 3 months ago now and still no creaking!!! Give it a shot, its an hours easy work and will save you £££££££££££

I have done this in the past on Honda ball joints, if a dry joint is your problem then this will sort it..

I've had this on my 987. In my case, it was the top mount on the drivers side going dry. Similar principle to the ball joint - spray some grease on there and if it gets better, then you've found the culprit. On mine it got worse when it was wet initially.
