Another Titan Bimmer pumpkin going south

[Reiver]

The r400D (2012) I recently purchased has the Titan virus and is clunking etc.... the elevated wheel spin test was a fail.  3400 miles.  I plan on getting a tracsport LSD to replace the innards or order the whole Caterham Titan w/tracsport innards in place.  I understand that is doable in another's comments sections.  I've sent TS an email so we'll see.

Just one of those things but that LSD must have major flaws to croak that quickly.

I emailed Steve perks in November. Thinking my Titan is in the way out. I ask about sourcing a new diff from caterham and installing the trancsport lsd into it. He said he could do it. Likely take 3 weeks once he has the caterham unit and would ship to USA.

he got back to me within a day or two.

I've emailed him and hoping for the same deal.

Mr. Perks has responded and can/will provide a Tracsport in a new Titan casing in my requested 3.64 ratio.  I am waiting for a reply on a Drexler for cost analysis.  Both are spendy but should never have to worry about this issue again.

Just for reference purposes, this is the other thread on the topic, right? 

 

The first post also has a PDF document explaining the root cause of the failed Titans and tips about it.

Given early failure probably had the carbon plates. Known issue as I assume you've discovered online. My 2020/2021 build presumably with sintered plates is doing well at >6000, mostly track miles. It has been very clunky at low speeds since day one, but still passes preload torque test with flying colors. All plated diffs are wear items. When mine gives up I will have to decide on Titan vs Tracsport for a rebuild/replacement. I guess depends on when it goes. I love the feel of it though. So much better than a torsen.

2012 build with the carbon no doubt in mine.... it is what it is.... failed at less than 3k miles.  If you read the 30 odd page of 'Titan Failures' some had rebuilds with the sintered that failed in short order.... much smaller plates size wise they said compared to other units. Then again, some are very happy with the later Titans.

Not taking the chance as it isn't cheap. 

If I were a track guy I'd go Drexler but the TS has a nice track rep too.... regardless, I've ordered the TS with a new casing and all internals.

If you don't track consider the quaife atb. Zero maintenance/wear.

Thought about it but want a better deal than that.  Any r400 deserves better than that

Steve Perks/Tracsport is getting a dif together for me in 3.64 presently.  He just received the wire/funds.  I'll update as things progress to establish a timeline.

He got back to me quickly with an invoice and wiring instructions.  The wire took two days to go thru (normal internationally).

I was in touch with him this week as well asking of any fitment issues I'd need to watch out for with a tracsport in a Sierra diff housing.   He was very helpful.

I'm still driving it anyway as I don't care what happens to this diff..... it is basically an open dif with toast carbon plates.  It clunks/whines but goes fine with no hesitation etc.... I'll not take any long trips but will drive locally.

I'll let you know if it totally croaks but so far so good lol.... iow, I don't care if it is rebuildable or not.
