Hi Rob
just noticed this.
Yes I've got the welded diff on now. It has made it a bit less usable as a road car, as low speed cornering, it skips about, and I think will tear the tyres up in no time.
As for drifting, well it won't make me a drift god in the short term, but I'm hoping it will help enough to convince me that I need a decent diff. And if it doesn't, then I won't have spent £400 plus on one, and I can just admit I'm never going to be much cop, but at least I've tried.
To weld it up.
1 Take off the back plate
2 Nylon mallet to knock the output shafts out
3 Undo the four bolts holding the bearing caps
4 Brass drift and hammer to knock the diff out of the casing via the output shaft holes
5 Remove bearings and spacer, noting where they all came from
6 Undo centre ring of bolts and remove differential gear, noting spacer
7 Weld the gears together, ensuring you get no weld on any parts that will interfere with the refitting of the diff unit into the carrier
8 Put it all back together
9 Go and play with the car, bearing in mind it cannot now be used for commuting, and people look at you when you go round corners because it sounds like you're wheelspinning and you feel a bit of a tit
