Thread: NOT lower control arms - Knocking problem in the front

Bump

Top shock mount, this could your problem, no rubber bush and when they go, they make a load knocking noise, assuming your's is a coiler and not air suspension.

I had a similar clunk / knock in mine, it can be many things with the most likely what you have done.
Another cause can be a worn lower steering shaft, pretty easy to replace. Fixed mine.

Check both inner and outer tie-rod ends.

Worth a try Redback, but no cigar.

Mine has air suspension.

I'll have a look at the mount though.

It certainly seems to be driver's side only, hard to find the right speed bumps that I can hit only with the drivers wheels.

There is a joint on the steering column in the engine bay that if not tight will rattle. Mine was left not properly tight after a body R&R.

Hi There,
As Graeme suggests check your tie rod ends into the rack, I had a knock similar to what you mention and found the tie rod end into the rack worn quite badly, didn't show much on the tyre wear which I found surprising.

Cheers Marty.

I had been chasing a similar noise for a while. Whilst the car was up on the hoist for other work, it had a thorough going over.

Inspection revealed both rack ends had play, as well as the lower steering shaft was knocking.

Now I'm just working through the part numbers to replace. I have a 2005 model also, and apparently there are different size tie rods on the earlier years. I found rocking the front wheel at 12 & 6 o'clock positions produced no play (bearings okay) but 3 & 9 o'clock produced the knock in the tie-rod ends.

My tyres also have no abnormal wear. All that I can think is that they are not being 'held' out of alignment and find an aligned position. Still pretty important to get it fixed though.
