	Yes alignment does matter, but the best thing to tell your mechanic is to scribe up the main eccentric bolt's position before undoing it, the head end, file a good clear mark on it, that faces exactly outwards. Then rotate it after re-assembly before retightening to that positiom, camber should be pretty close after that.		'''HaryyMann:'''

			1) Yes alignment does matter, but the best thing to tell your mechanic is to scribe up the main eccentric bolt's position before undoing it, the head end, file a good clear mark on it, that faces exactly outwards.

	Make sure the full weight is back on the suspension (jack lower wishbone up) before tightening that main eccentric bolt, the bushes are not bearings, they're rubber bushes not intended to move, so you don't want that rubber in permanent strain.		2) Make sure the full weight is back on the suspension (jack lower wishbone up) before tightening that main eccentric bolt, the bushes are not bearings, they're rubber bushes not intended to move, so you don't want that rubber in permanent strain.

			3) 2WD and Syncro are different, 2WD bushes need MIG tacking in place.

	~~2WD and Syncro are different~~, ~~2WD bushes need MIG tacking~~ in ~~place.~~		4) Yes, exact alignment before pressing them in is best - garage should have a 5 ton press (usually)

	~~Yes~~, ~~exact alignment before pressing them~~ in is ~~best - garage should have a 5 ton press~~ (~~usually~~)		5) Eccentric spacing washers come in 3 thicknesses, but normally the originals suffice. Sometimes (on a syncro) the new ones push in further and there is far too little clearance to get the original eccentric washers in place; Either get smaller ones (5mm, 4mm, 3 mm?) from VW, or if veryu tight in arms, can drift the bushes back out equally till they 'just' fit

	~~Eccentric spacing washers come in 3 thicknesses~~, ~~but normally~~ the ~~originals suffice~~		6) The OEM VW bushes are different to all the cheaper replacemetn bushes, and are the best to use.. it has been known that certianly Mehle style upper wishbone inner bushes can fail very quickly (< 1 year)

I had big problems getting the bush to initially bite on the edge of the wishbone. Everthing was now covered in copperslip. I was sweating like a horse. And the combination made holding, banging, gripping near impossible.

	When you took it off you marked up the eccentric bolt that held it all together, so you could re-assemble it properly, right? Well that's pretty immaterial if the bush is proper knackered, cos you're gonna need to take it and get it re-set afterwards as the new bush will move everything around and I'll get you don't have a wheel alignment set at home, do you?
