Parts needed to install a LSD on a DSG

Ah that's good then.  Some LSDs don't come with bolts (Quaife).  Peloquins supply them, not sure about Wavetrac.


--- Quote from: MFactory ---No-Load/One-Wheel Syndrome
A common misconception is that a Torsen-Style Differential is useless under a no-load situation (e.g One wheel in the air). This myth has been further perpetuated by our competitors of whom have limited understanding of how a Torsen-Style LSD functions. This no-load situation does not apply to 90% of users. For the other 10%, there is a simple solution to the problem that our competitors will not tell you; simply tap your brake pedal.

That isn't a myth.  I had no-load situations more times than I can remember with my Quaife, and that was on the road and not pushing the car that hard.  There's usually around a minimum 5-10% preload bias the opposite axle needs to see, otherwise it will spin the unloaded axle.....just like an open diff.   Very true about the brakes though, which is why an LSD in combination with the ABS traction control is a good thing.  Shame the latter only works up to 25mph.  Handy for getting you moving on snow/ice though.

Hmmmm, you can take that with a pinch of salt.  Sales pitchy speak.  FWIW, my Quaife lasted well over 80K miles daily use before I sold the car, and it's made with inferior materials :smiley:

Apart from the usual sales chatter, it looks good  :happy2:

A track day friend and dyno tester gave me bad feedback about Quaife LSD. Told me that he knew a few cases needing repair. Being more expensive didn't help its case either. :slap:

Forged over milled steel sounds good. I can only find good feedback on American forums about this LSD so that pretty much made me go for it.

pudding:
Yeah it is expensive for sure.  They are long established in the business though and I've not personally heard of any failures.  I punished mine with VR6 Turbo torque (a lot more than tuned TFSIs kick out) for 6 years with no issues  :happy2:

Anyway, an LSD is better than no LSD, so you'll have some fun  :smiley:

Well, to finish this topic I wanted to share my knowledge now that my DSG is opened.

The differencial bearing 002517185M, which is the same as the manual gearbox has, corresponds to SKF part number: LM 503349/310 or BT1-1767/QCL7CVA607 (45.987x74.976x18.000).

The other differencial bearing that I couldn't see the part number on ETKA has the following part numbers: SKF LM 102949/910 or BT1-0251/QVA621 (45.242x73.431x19.558).

spb:
How difficult do you rate the operation to be? Does mfactory provide any instructions?
