Wez Posted October 13, 2005 Share Posted October 13, 2005 Thanks Chris, This may be a silly questions then but how does the TRD unit work better than stock unit, if you have a stock LSD and TRD LSD whats the difference or am i missing the point here and there was no stock LSD?

Chris Wilson Posted October 13, 2005 Share Posted October 13, 2005 The TRD is a plate type, with much more limited slipping The stock LSD is a gear type, with very little limited slipping. makers fit gear types as they are cheap, maintenance free, and unlikely to put granny in the weeds if she can't drive.

Justin Posted October 22, 2005 Share Posted October 22, 2005 Mark Brown and Syed Shah both have units fitted by me (but bought in the USA). Possibly the single biggest traction enhancer available for the MKIV. The stock type LSD is neither use nor ornament, to be frank. Chris what diff make/model did you fit to Mark Browns car? Because that is my car now and I just wondered. Is it normal for oil to leak out? Will post pics later. Quote Link to comment Share on other sites More sharing options...
Justin Posted October 22, 2005 Share Posted October 22, 2005 Not saying it is anything you did of course!!! I just noticed it today when changing wheels. It's the same both sides. Quote Link to comment Share on other sites More sharing options...
Pete Posted October 22, 2005 Share Posted October 22, 2005 Your diff seals are going. No, it shouldn't leak out.. Worth checking the diff oil level or doing a change if it's been like this for a while to avoid it starting to whine and then damage. Having said that I'm sure it's quite normal on a 10 year old car! Best thing to do is wipe it all off and check how it looks after a few hundred miles to see if it's leaking much. Quote Link to comment Share on other sites More sharing options...
suprabrown Posted October 22, 2005 Share Posted October 22, 2005 Hi justin....... I'd better check the garage...........................the car was still there this morning I think you must have a different mark brown (common name!!) Don't know if CW has worked on your car, but it's mine he is talking about in the earlier post. But...... it does look like your seals are buggered When we put the LSD in chris fitted new seals -- Nic can sort you out with the correct parts if needed cheers Mark Brown Quote Link to comment Share on other sites More sharing options...

Doh what were the chances. Yup reckon you guys are right that the seals have gone on my STOCK diff. Small parts but big job am I right? Both drive shafts look very rusty too! Carbon fibre ones would be nice. Has anybody here replaced their LSD seals? Any info, tips, costs appreciated. Quote Link to comment Share on other sites More sharing options...
Chris Wilson Posted October 23, 2005 Share Posted October 23, 2005 Follow Petes advice, it may be the stub seals leaking. They shouldn't leak, but they were not renewed, I have never seen them start to leak after an LSD has been fitted before. Odd... Diff is a TRD plate type Mark supplied.

Pete Posted October 23, 2005 Share Posted October 23, 2005 Follow Petes advice For the record I was under my 94 NA today and there isn't a sign of leakage, so maybe not as common as I thought after all. Quote Link to comment Share on other sites More sharing options...
Chris Wilson Posted October 23, 2005 Share Posted October 23, 2005 Oh, THAT Mark Brown! I don't believe I fitted an LSD to that car, did I? And I just checked, Marks car that I DID fit the LSD to, DID have new side seals and a new front seal. Quote Link to comment Share on other sites More sharing options...

No you didn't Chris you fitted a Volvo oil cooler into the front of my car Mark Browns car years ago. Sorry about the mix up. So I should replace the main oil seals between the diff and each drive shaft. Anything else I should renew whilst all these bits are off?

Chris Wilson Posted October 24, 2005 Share Posted October 24, 2005 Just fit new side seals, should fix it. Can be done in situ. Quote Link to comment Share on other sites More sharing options...

Chris Wilson Posted October 24, 2005 Share Posted October 24, 2005 On the subject of TRD diffs how complicate is it to fit the internals? it's easy to fit the internals, a royal PITA to set up the clearances and preloads though, which needs to be done when changing the crown wheel carrier. which is part of the LSD kit. NOT for the feint hearted at all.... Quote Link to comment Share on other sites More sharing options...
neo1 Posted October 24, 2005 Share Posted October 24, 2005 I have one.... I love it, also had one in my MR2... Can be a pain in the wet but fantastic in the dry. Quote Link to comment Share on other sites More sharing options...
Miguel Posted October 24, 2005 Share Posted October 24, 2005 On the subject of TRD diffs how complicate is it to fit the internals? It's an absolute piss of piss to fit and set up Termy. There is nothing complicated at all ..if you can fit an RB lump into a 200 then this will be like picking your nose Took me about an 1 to 1 1/2 hours all in .

That is quite a differing opinion to CW, care to explain a little? On subject of diffs, if you track your car, or drive v. fast on the road, get the TRD one, no regrets, best mod ever.

The actual main unit itself to swap is a breeze the most " complex" is setting up the lash, gear tooth contact, pinion preload. It's fidly but in no way complex. If anyone can shim up a set of cams they can do this. It has to be done also when checking a normal diff and all the tolerances, specs and walk throughs can be found in the tsm manuals ...you just apply the specs that come with the diff. Like I say fiddly but not complex. Quote Link to comment Share on other sites More sharing options...

Yup it does sound good Syed, very tempted but would it swing the back end out and be harder to 'straight line' race? ie drag strip. Quote Link to comment Share on other sites More sharing options...
Syed Shah Posted October 24, 2005 Share Posted October 24, 2005 Nope, tracks straighter, making drag racing easier. In the US, it is about the only mod shared by the hardcore drag racers and track racers. Quote Link to comment Share on other sites More sharing options...
MONKEYmark Posted October 24, 2005 Share Posted October 24, 2005 thanks for the diagram of the diff. i have a spare non lsd diff.would like to strip it down see how its made up. Quote Link to comment Share on other sites More sharing options...
