Right done it

not to bad really, few differences with Ronald Mcburger's method though
http://www.omegaowners.com/forum/YaBB.pl?num=1158598664 :-?
1. Both the rear idler to bracket & the front idler to steering arm were 18mm?
2. Struggled to get the old idler off, managed in the end by getting big bar in on top of the steering rack right on the idler joint and then levering towards front of car under the wishbone mount - then tw4t the idler up with a big hammer till it 'pops' off like Ron says

3. When i came to tighten up the new idler onto the s/rack joint it kept turning so i used a trolley jack under the joint to put pressure on it so that the tapper gripped

4. To torque the idler to steering rack joint there was insufficient room to get a torque wrench in from the wheel arch :-/ but if you centre the steering i found that with 3 extension bars (approx 2 foot!) you can get on to the bolt through the engine bay between the oil filler (V6) and the scuttle

All in all not too bad, hardest part was getting the old bits apart as usual

Took it for a run down the road and i hadn't realised how bad the steering must have got over the years

It's
SO much nicer to drive now

, tighter

, doesn't wonder or tramline

and the 65mph speed vibration has gone
