rakas17 Posted July 3, 2011 Report Posted July 3, 2011 just got back from santa pod, I did the 1/4 mile on saturday and since then my diff has been making some horrid noises. I put the diff in about 2 weeks ago and have done a few donuts and stuff and started hearing a few nocking noises coming from the back, i figured it may have been suspension stuff and put my anti tramp bars back on as theyve been off for a while. After 3 runs up the strip yesterday it was making a really loud squeaky noise and a bit clunky and knocky but only when i was making tight turns like parking and turning round. I asked a guy that looked like he might know with a mk1 and he was pretty up on diffs and told me that it was normal as they get hot and wound up when you do burnouts and stuff. this morning wasnt as bad but when i drove from the camping field to the show bit it was definatley still there. I've just drove it home and every roundabout and junction was really clunky, not so much squeaky but really knocky and a bit grindy. doesnt sound good. i bought the diff already in the pig head bit with a 3.89 crown wheel and pinion already in there, from an autojumble stand at the classic ford show. Its a tranx and apparantly brand new, it looked new. i paid £420 for the lot so thought i was getting a bargain. by the way, my best time from the 3 runs was 15.25 @88mph. pretty pleased with my first ever go. I wanted to do some more runs today but obviously was worried about this. thanks for looking guys, any advice welcome. Joe p.s. I tried to find someone with a stand pass last night but had no luck so i stuck it in the show and shine bit today.
Stiggy Posted July 3, 2011 Report Posted July 3, 2011 Sounds like it's set to tight. Sure Mr Grumpy (Wayne) at WPE can sort this out EDIT: If it was on of Ricky's then yes they are indeed brand new.
rakas17 Posted July 3, 2011 Author Report Posted July 3, 2011 it was from some welsh lads, i asked for a receipt and he wrote "3.9 lsd £420" on a bit of paper from a hello kitty pad. so i asked for their number and he pulled out a bit of hello kitty pad with his number in biro on it from his pocket.

rakas17 Posted July 3, 2011 Author Report Posted July 3, 2011 haha, yeah i know but it looked good and to be fair, was working fine until recently.
Stiggy Posted July 3, 2011 Report Posted July 3, 2011 My old GKN (Burton RS Part)LSD was forkin noisy till I got Roland at HT to adjust it 20 years ago.
Stiggy Posted July 3, 2011 Report Posted July 3, 2011 Clonking. Grinding/Groaning. Screeching, just horrible noises, like there is no oil.
rakas17 Posted July 3, 2011 Author Report Posted July 3, 2011 Pretty sure it hasn't leaked. I sealed it with silicon and it still looks clean.
Stiggy Posted July 3, 2011 Report Posted July 3, 2011 Pretty sure it hasn't leaked. I sealed it with silicon and it still looks clean. No. Sounds like it had no oil. My old one not yours.
rakas17 Posted July 3, 2011 Author Report Posted July 3, 2011 Yeah but are you saying it made those noises and there was oil it just needed adjusting? If so then thats good news I guess.
Stiggy Posted July 3, 2011 Report Posted July 3, 2011 Yeah but are you saying it made those noises and there was oil it just needed adjusting? If so then thats good news I guess. Yep tried so many different oils, rebearing about 5 times including correctly setting up crown wheel and pinion backlash. (I worked at a Ford main dealer at the time) All made no difference it was set to tight for road use. Once adjusted it made no noise.
rakas17 Posted July 3, 2011 Author Report Posted July 3, 2011 Cool, got any good suggestions of where to take it? I'm in Herts.
w p e Posted July 3, 2011 Report Posted July 3, 2011 newer tran x slippers do click and clonk as the clutch plates are set a little tight its common for these noises it can be adjusted internally to stop most of this noise. what oil did you use?

rakas17 Posted July 3, 2011 Author Report Posted July 3, 2011 Oh, is that where wpe is based? Cool, I'll give em a call tomorrow.
rakas17 Posted July 3, 2011 Author Report Posted July 3, 2011 just spoken to a mate thats used W.P.E and i think it might have been mr wpe that i randomly spoke to about it at santapod!!!

I used limited slip oil, and i put a litre in.
MK2Ed Posted July 4, 2011 Report Posted July 4, 2011 Needs filling with oil till coming out of your axle filler plug. Will need setting up for your application, eg track/race set ups will be different from how you want it for mainly road use. Setting up should cure it or either that or your CWP has lost some teeth following donuts as happened in one of mine once
rallyesport04 Posted July 4, 2011 Report Posted July 4, 2011 i had a tran x lsd new after a few times of hard use it also clonked an grooned took it out had a look all was well its just the way they are
rakas17 Posted July 4, 2011 Author Report Posted July 4, 2011 Well I was advised by wayne to do some donuts as it might free it up a bit, so heres me trying to fix my car... It probably sounds worse now, I think I'll whip it out and have it adjusted to be a bit more road use friendly.
Stiggy Posted July 5, 2011 Report Posted July 5, 2011 Nah I'm just playing with yah. They do get nosier after some stick, but not always, if they are set tight as they warm up they get nosier. But it's only an annoyance.
gearbox100 Posted July 5, 2011 Report Posted July 5, 2011 Might be worth getting it checked out just to be sure . A few years ago now i remember we done an mot on a customers mk2 rally car , when i reversed it off the pit the diff made all sorts of noises and i said to the owner that the diff wasnt right , he told me that it was a lsd and they all done it , i tried pointing out i knew that but his still wasnt right even for a lsd , he told me that i was a young lad and didnt know what i was on about . The day of the rally came and 5 miles into the first stage his diff broke and he was out of the rally . He could of saved himself loosing alot of money if he had just listened to the idiot young mot test station lad .
