James Posted May 16, 2012 Share Posted May 16, 2012 Got in the car this evening and when I changed from 1st to 2nd I had a pretty hefty clunk/thud at the rear end. It was then happening when the car was just driving along and I changed throttle position and also when turning at junctions. I didn't use it for long (a mile or 2) and so haven't had a chance to jack it up and assess anything. Would it be an issue with the diff or with joints of some sort? How much is a 2nd hand A01B 4.083 LSD to buy and is it an easy job to change? The car has been going good for the last while too, typical something happens now! Thanks!

Josh Posted May 16, 2012 Share Posted May 16, 2012 Mine clunks when going into 2nd and reverse when cold sometimes. I think a few people have this, so I put it down to the characteristics of the diff/gearbox. http://www.mkivsupra.net/vbb/showthread.php?253852-Clunking-noise-in-rear-when-changing-gears-What-can-it-be&highlight=clunk Quote Link to comment Share on other sites More sharing options...
James Posted May 16, 2012 Author Share Posted May 16, 2012 It is the first time it has happened in 3 years of owning the car and it isn't just a noise, there is a big judder when it happens. Can definitely feel it! That is why I'm quite concerned! Quote Link to comment Share on other sites More sharing options...

Can definitely feel it! That is why I'm quite concerned! I feel a bump too. If the handbrake's off, the car moves slightly too. Weird that it's just started, though.

Dnk Posted May 17, 2012 Share Posted May 17, 2012 (edited) Check the calipers to make sure their not seizing would be the first thing i'd look at as this is now a common problem especially with the smaller j spec brakes as they have a sliding caliper set up in which the pins the caliper moves on seize up along with the pistons seizing if the outer seals have failed. Then i'd check the cv joints on the drive shafts and also the diff and propshaft while your at it.

I only recently - less than a year - fitted some UK specs but I shall check in case they are seizing. It doesn't seem to pull to one side nor am I restricted in motion. Yeah I'll have to check the rest too! Knowing my luck it will be whichever part is most expensive! Sub frame? I checked these about 2 months ago and all was ok, I suppose best to again!

Pig Posted May 17, 2012 Share Posted May 17, 2012 It sounds like something might be coming loose. Always best to check the cheap and easy stuff 1st. Quote Link to comment Share on other sites More sharing options...
Camry5Sgte Posted May 17, 2012 Share Posted May 17, 2012 I have the same noises only from the front... turns out to be engine mounts. Quote Link to comment Share on other sites More sharing options...
James Posted May 17, 2012 Author Share Posted May 17, 2012 Ok it's definitely the diff because it is now knackered completely and won't move unless the wheels are completely straight and even then it hops over what I assume is a/many broken tooth/teeth. How much is an A01B LSD and how easy/hard are they to fit? Quote Link to comment Share on other sites More sharing options...
