I've owned a manual 2010 FG XR50 Turbo for a couple of months now and I've had a bit of a saga with the car so far. Diff bush was shagged (got the usual thud when backing off after WOT and between hard gearchanges), so I got ALL the bushes changed in both the front and the rear (that's not overkill, right?) to Super Pro bushes (except the control blade bushes...they forgot to do those somehow), with comfort series outer diff bushes and a solid centre bush, as advised by Pat from Wholesale Suspensions due to the car being a manual. I also got some Teins fitted while I was at it (Thanks Pat!). Once I got the car back the original thud was gone, but now I noticed my diff was whining and there was a clunk coming from the back somewhere. Chucked the car up on a mates hoist and noticed that there was oil leaking from one of the side seals in the diff and that the attached halfshaft had a bit of play in it that would make the same clunk I could hear from inside the car. So off to WA Diff Centre and had my diff rebuilt with all new bearings and seals and a Harrop TrueTrac centre. I was worried about the whinning still being there so got a little carried away and got the to change out my solid centre diff bush for a comfort series bush just incase, they also fitted up the Super Pro comfort series control blade bushes for me that the suspension place forgot to install. Now that I have the car back the whining and clunk from the diff is gone but the original thud is back, albeit not as bad as previously. In hindsight I really should have just stuck with the solid centre to see how much difference there was with the rebuilt diff, as now I don't have a direct comparison. Could this just be an issue with running the comfort series centre with a manual? Is it worth throwing the solid centre bush back in to see if it gets rid of the thud, and just hope the whining and clunk don't come back? Also, today I noticed a noise I've never heard before. I was sitting at a red light and when I pressed in the clutch and put the car into first gear I heard and felt a clunk from somewhere in the driveline (whether it was from the gearbox or from the rear I can't be sure). This clunk was NOT there before, even with the solid centre diff bush. I can replicate this noise most times and I found it's more pronounced if putting the car into 2nd gear when not moving and keeping the clutch to the floor. Any ideas what this could possibly be? When I had the car serviced a couple of months ago I was told by the mechanic that the clutch slave cylinder is on its way out...is there any way that could be starting to get worse and causing the clunk with the gearbox? (this probably shows how unmechanically minded I am). The only other thing to note about the car is that it clunks rather loudly from the front (gearbox?) when maneuvering at low speed. My housemate came out while I was reversing into the driveway a few weeks ago and commented on how loud and clunky it was outside the car. From what I've read in other threads this seems fairly normal for these cars?
