#130 Same here, I was considering an upgrade from open to LSD over winter. The problems relate solely to the Titan unit so obviously I wouldn't consider fitting one of those even with a meagre 120hp. 
 

#125 ScottR400D do you know if that applies to the BMW open diff? ie " It is designed to fit the BMW housing and the standard driveshafts. A matter of removing the diff as a whole, getting it to Steve Perks, getting it back and refitting.

Yes, of course. When my original LSD failed damaging the CWP, I bought an open BMW diff from CC and had it sent directly to SPC. 

Steve installed his LSD, I collected the assembly and refitted.

#131. I think that’s a fair point but the Club is more than just Blatchat and they do act in many other areas on behalf of the members, so why not in a case like this, if it’s worth acting on?

We’re not talking about legal action, I wouldn’t think, just one body making a joint approach on behalf of those interested. (Not that I think it’d make much difference with CC/Titan)

Having said that, the Club’s leaders seem to have been quite prepared to act like a firm of lawyers in the past............ Wink

That was under the old management!

In the past the club did have a technical group that liaised with CC. One of the biggest successes was when the Sigma cars were launched convincing CC that there was an inherent problem with the engine management, that the radiator plastic header & footers were faulty & a large batch of front flexi brake hoses were faulty. 
CC listened & slowly rectified all to some extent.

#111 - 113 Geoff, Scott & James Thanks for taking the time to reply. My ' worry mode Eek ' stopped me noticing that the thread targets BMW diffs, rather than Ford. That is some piece of mind as I can now use the car without worrying it's going to self-destruct. Now just need to find out what I do have to guide the next decision!

#138. I think that’s likely the case Dave, because, as I understand it, the Titan came along roughly in line with the BMW housing and so is mostly in them. 

Previously the Fords had various options but not the Titan, though there may be some overlap.

So is my 2011 Titan/Ford "at risk", or is this only a BMW/recent plates/200+ bhp issue?

 I did the checks, wheels spin together, but 20lbft preload. I've no clue what the orginal preload was. No increase in noise. 
 

What is the effect of reduced preload? Oversteer/understeer?

Thanks

AB, I’m just guessing but perhaps you have the original carbon plates which appear to have been the best version of Titan LSD. 

The story is that at some point they ‘changed’ and began to wear very quickly hence the introduction of the sintered metal plates. 

Current thinking seems to be that preload starts off at about 40lbs ft. When that’s down to 20 it’s time to be planning a rebuild, much below is close to full failure. I guess because the reducing preload indicates increasing wear of friction plates and springs. 

Maybe if the earlier carbon plates didn’t wear so fast they could start with a lower preload and yours is OK at 20? 

A lower preload, as far as I know, reduces the initial amount of locking, which would reduce any understeer induced by the LSD.
