Lower wishbone bushes
Discussion
I've come to offer up the new bushes into the various front suspension bits, and everything looks good except the ones on the short side of the front wishbone which are very loose (best part of 1mm play in them).
Has anyone else had this issue? Is there a simple solution other that going back to Polybush and getting them to make me up some slightly larger ones??

I was trying to fit the wrong bush. There's a packet that's labelled "Front wishbone" with a total of 4 bushes in it, so I'd assumed that was the one.
It was only 2 mins after I posted that I noticed that another packet was labelled "Front wishbone uppper mount", and that one fitted perfectly.
The first packet is the bushes for the upper and lower rear mounts.
Not quite as stupid as not RTFM, but close.

How are you getting the old bushes out? I am dredding this job. I was thinking about buying one of these to help....

I don't think it'll do it.
I made up a "press" using 12mm stainless threaded bar, packed it out with washers and wound down the biggest nut that would fit. I moved one of the bushes about 1mm before I snapped the bar. Not sure what the tensile strength of a 12mm bar is, but I'd guess its quite a lot.
Oxy and a reciprocating hacksaw FTW.
Being different, I had my local engineering place make up a couple of "blanks" - solid metal cylinders which fitted the holes to ensure a perfectly straight push, and then pushed the bushes out using their 50-ton press. Even after the blanks were made it still took 3 1/2 hours to get the b
ds out - and that's just the fronts.

I bought one of those over the summer to do the bushes on the Mk1 Golf track car & the front wheel bearing on my commuting car (Seat Toledo) as it was cheaper for my to buy the press & do the work than pay a garage.http://cgi.ebay.co.uk/12-Ton-Industrial-Hydraulic-...
I've used it twice, and it's already paid for it's self ! Next week it'll be being used again to do front lower rear wishbone bushes & rear trailing arm bushes on the BMW 328 - it's amazing how much you use it once you have one ! (I paid £70 for mine)
You'll get more stree releif from using a 8100dy great big mallet & chisel/bar though......
Get them to try doing one (I found the long side of the upper wishbone was the toughest), if they're going to give you a quote based on an hourly rate.
Oh and if they're going to use a super-mega-ton press, make sure they're mounting the arms completely square. It would be so easy to distort an arm with the kind of forces we're talking about here.

Sounds like a good idea!Oh and if they're going to use a super-mega-ton press, make sure they're mounting the arms completely square. It would be so easy to distort an arm with the kind of forces we're talking about here.
