Rear brake pads mate. Do a search and you'll find threads about the retention springs in the calipers allow the pad to move in the bracket, making a clicking noise.

 

If your diff is knackered, it'd be the first one I've ever heard of going. Also, have you seen the size of the diff on these cars, its MASSIVE, its looks very substantial and a capable bit of equipment for the car.

 

Diffs also make a droning noise or whine when they go.

just a quick 1 lads.....i have a 1993 none turbo and ive done 3 diffs so far!!!! when a difs broke the click and grind.i do trackdays and some drifting and it just kills the standard 1s.upgraded to a 99 turbo one and seeing how it goes.

 

Not sure if you're asking a question here, but if you're using the NA diff they are not all that strong. If you're doing drift days it's presumably an LSD NA diff and blowing out the crown wheel, have you considered getting a stronger crown wheel installed?

 

The '99 NA diff is the same as any other NA one, so it won't be any stronger. If you're using a "turbo" one, is it from an TT or auto? The drive ratio will be much lower, so will be higher geared, you'll have a hard time getting it to break traction and suffer from long gears. The Diff itself is the same on the NA and TT LSD with the small casing, only the crown and pinion are different.

wow you know your stuff! appreciate your reply!! (i should have joined on here a long time ago!) basicly i use my car on the track with the odd drift here and there,it just gets nailed 24 7 to be honest.my car is a 1993 none turbo 5spd manual and as i said ive broke many and as you rightly say the standard ones just are not up to the job if your nailing it as i am.as you will no when you get parts from wreckers they will tell you anything to sell the part...i cant be 100% what the diff is! (although they said its a 99 turbo) when we fitted it we had to change both external cups on each side which the drive shafts bolt on to (took my old cups off the broke diff and fitted then to this one) as they were different and we also had to change the triangle part the prop bolts on to (im no expert with stuf like this my mate workes for toyota so he does it all) ill find out when i drive it but if the gears are slightly longer i wont mind to be honest as long as the diff lasts.i did say to my m8 if it goes again ill have to look it to the problem.get ready cos if i get an issue im coming straight to you.ha many thanks!
