Dazzi Posted February 24, 2012 Share Posted February 24, 2012 For a while when i change gear or let off the throttle i hear a noise coming from the diff. I got the car up and held the propshaft and turned it left and right. There seems to be a bit of play when doing this. If there anything I can do. AFAIK its an LSD on my NA.

JamieP Posted February 24, 2012 Share Posted February 24, 2012 There will be play if you turn the prop like that, might not be the diff. Quote Link to comment Share on other sites More sharing options...
ManwithSupra Posted February 24, 2012 Share Posted February 24, 2012 You sure its not your diff mounts, suspension arms, suspension top mounts etc? If you are a changing gear and letting off throttle your shifitng the weight of the car back and forth. Quote Link to comment Share on other sites More sharing options...

Scott Posted February 24, 2012 Share Posted February 24, 2012 Sounds more like the exhaust bumping something when you let off. Quote Link to comment Share on other sites More sharing options...
Dazzi Posted February 24, 2012 Author Share Posted February 24, 2012 Diff fluid already changed and no bits on the plug. The exhaust is totally clear of touching anything. Quote Link to comment Share on other sites More sharing options...

If it's definitely the diff you will notice it when moving forward and reverse slowly over a short distance, ie when parking. I doubt it's going to be the diff, more than likely the mounts, subframe bolts or suspension as mentioned earlier. Quote Link to comment Share on other sites More sharing options...
Dazzi Posted February 24, 2012 Author Share Posted February 24, 2012 Yea it knocks when im moving slowly i.e parking and getting into reverse. If im stationary and i lift the clutch up enough for it to bite it does it again. Quote Link to comment Share on other sites More sharing options...

If im stationary and i lift the clutch up enough for it to bite it does it again. What about if you try to push the car (forwards and backwards) with the engine off and in gear? If you can replicate the noise then, and not when it's out of gear it would probably point to the diff. I'm just thinking off the top of my head though, trying to think of a test you could do, so that's maybe nonsense. I would give it a go though.

Dazzi Posted February 24, 2012 Author Share Posted February 24, 2012 Thats a good idea. I'll try that in abit. Cheers mate. Quote Link to comment Share on other sites More sharing options...
Scott Posted February 24, 2012 Share Posted February 24, 2012 Try it with the handbrake on when it's not in gear. That way you will be putting pressure on the arms & suspension rather than just rolling the car forward Quote Link to comment Share on other sites More sharing options...
David P Posted February 24, 2012 Share Posted February 24, 2012 If im stationary and i lift the clutch up enough for it to bite it does it again. Get someone to listen/look for it's whereabouts whilst you make it clunk. Quote Link to comment Share on other sites More sharing options...
Pulley Posted February 25, 2012 Share Posted February 25, 2012 Jack the rear up and put in gear, grab thewheel and rotate back andforth (or get a friend too) and look for backlash, noise ect, can hold the driveshaft and isolate the diff/ rear shafts, start at gearbox propsgaft and work back Quote Link to comment Share on other sites More sharing options...
Dazzi Posted February 28, 2012 Author Share Posted February 28, 2012 Had the car up today and the prop going directly into the diff turns about an inch either way. It makes a clunk if you twist it hard. Quote Link to comment Share on other sites More sharing options...
Dazzi Posted March 1, 2012 Author Share Posted March 1, 2012 Update. Got the car up again and went up the propshaft looking for play. The propshaft slider seemed to be stuck so i twisted both props in opposite directions and heard a pop. The knocking when reversing and booting it/foot off throttle has now stopped.
