Title: Fitting a LSD - few questions
Post by: Syrag64 on December 20, 2013, 09:22:17 pm
I have the LSD, complete new clutch and have just ordered the 2 diff bearings & shims, I also need some sealant, VW quoted £60 for this, can I use an alternative thats cheaper?

Also on my car at the moment sometimes the clutch pedal stays down and I have to lift it with my toe, do I need a new master or slave cylinder?

Also I am going to fit new engine mounts, is there anything else I should do whilst I'm doing all this?

Factor in a wheel alignment also as I believe the subframe has to be removed  :happy2:

Your driveshaft would need to come out, subframe stays in place. I've done my gearbox (on my TDI same method exactly) 5 times. Never needed an alignment afterwards.

The issue you mention regarding the pedal is indicative of a slave cylinder failure.

As your Subframe is off for the clutch bits why not fit a new uprated front anti roll bar too, perfect time!  :wink:

Would be a good time to do it but you don't NEED to drop the subframe it gives very little extra space to be honest.. !! A waste of time IMO.

You don't need to take the subframe off to do the roll bar either, undo the bolts a bit and it'll drop down enough to get the bar out.  :happy2:

Your TDi was 5 speed though?

Yeah it was.

6 speed Mk4 is a bit more tricky.  From the DIYs ive read of a MK5 GTI (having done my TDI one countless times, got bored of it in the end  :signLOL: :signLOL: ) you dont need to remove subframe on these either.

Happy to be corrected if tjatthat's the case :)

5 speed falls out.  6 speed removal and fitting is far faster with the subframe removed.  I mark the subframe positions so it 99% back in the correct place.  It can be done with the frame still on, but its an arse.

Any differences in effort between fitting on a manual vs DSG?

You have to be very careful when cracking open the DSG box as it needs to be separated from the mechatronics unit when getting at the diff. Oil refill needs a tool to do too.

Loads more effort. A lot more to mess up too. I've done enough of them now to have a good routine to get them right.
