·Guess what?
My Evo is sick again. This time I am getting a regular clunk on full right lock. Its quite loud and certainly can be heard above the engine with the windows shut. I instantly thought CV joint and booked the car in (Wednesday this week) for a check. I have had a look at it today and and the driveshaft feels fine to me with hardly any play in it, in fact the left and right driveshafts feel the same. I have also checked the anti-roll bar and suspension bushes and they look and feel solid as far as I can tell. Of course when the car is jacked up it doesn't make the clunk (typical but I assumed it wouldn't anyway) so it is making it hard to diagnose.
I am starting to suspect the steering rack as there is quite a marked gurgle (possibly air but it just sounds like fluid moving) when moving from lock to lock. The fluid level is fine, actually a while back I had to take some out because it was over filled and leaking out the top, it is now on the Max mark. I have tried bleeding it (hold it on full lock for 20-30 seconds with the pump going) and it has made no difference so there could possibly be a leak sucking air in (thanks Paul for the info). It could also be a problem with the stop in the rack. Is the rack supposed to be silent? (I am talking about listening to it while under the car)
Before I condemn the rack however, I have heard that there is a problem with the top suspension mounts on the E6 with them drying up. I doubt that it would be this but could they cause a regular clunk (e.g. once every rotation of the wheel) and at no other time than on full right lock or just off full lock?
I sorted out the top mounts on a TR7 I had (cough, cough did you hear that, no? good!) just by cleaning them up and re-greasing them. The only symptoms of the problem with those was a squeak but it was all the time and not just on full lock.
I know its difficult diagnosing problems from a distance but any suggestions would be appreciated.
Watch out for a new thread......'How reliable is your Evo?' sigh
