If you don't want to read that link .. short story is : Going for a full Geo Monday so I check the rear control arms - seized, so I "tried" to free one, and failed in a spectacular fashion .. 2 new ones ordered at £83 each.. and probably VAT to add to that.
Going back through my receipts, this car has been to WIM three times; June 2009 (86852 miles) after wishbones changed, September 2010 (101071 miles) after drop links and front TRE's (busy Newent that was!), and September 2011 (110176 miles) after wishbones, steering idler, front wheel bearings.
On EVERY occasion the rear "geometrical driving axis" was -0.04 (target 0.00 +/- 0.13) ... so well "within limits".... and therefore, apparently, not touched.
The only work on the rear (other than brakes etc) that has been done since the last time is a new nearside rear wheel bearing, a replacement diff, and polybush rear doughnuts.
I don't see any of those changing the rear alignment (although I could well be wrong) .... so
Should I have left "well alone" and saved myself: around £200 in parts, £50 in tools; 2 1/2 days, a fair bit of blood and skin, god knows how much that I SHOULD have put in the swear box, and a large number of paracetamols ... ??
They have obviously not been touched since I bought the car in Jan 08 with 70981 miles ....
Car now has 136382 miles .. so the Lemforder wishbones lasted 26,000 odd miles
