Mr Haynes doesn't list a "pinch bolt" .. and I'm not sure what else to call it ...    options are (as best as I can work it out)

Lower ball joint to arm... 35 NM  (thats the one I went for)

Lower ball joint to knuckle ... 100 NM   ( should it be this one ?? )

Lower suspension arm pivot bolt (120 NM + 2 angle tightens) .. (I guessed these were the front/rear wishbone bolts)

:(

100nm is approx 75 ft lbs that will be way to much for that little pinch bolt

they are quite common and like most thirsty big tanks worth very little.

The Stag's vapour pressure drops pretty markedly when powering a 3.2 on full chat. Wouldn't fancy one on anything more powerful.

If Entwood was not so sure of the sudden change in wear, i would suspect the original set up...? Esp strange that both sides would appear to alter/wear at the same rate(i presume)? Whats the odds on that?

Entwood, when i changed my front shocks i use an 11mill socket as a feeler gauge(diameter, not length) between the shock body and rim. If you want to use that as a guide you shouldnt be too far out as my set up was bog on. Didnt need adjustment. We have the same socket set iirc. Bit of a fiddle though as it took a couple of attempts and i kept dropping the socket on the hub assembly.

Re vapourisor. Where from and how much? Mine has a very pronounced hic up. Sometimes shows when changing from 3rd to 4th(auto box) or when lifting off the throttle at high revs in a high gear. Can be avoided by lifting off gently, not always possible.

Thread Hijack!!!!

I thought the Stag Vaporiser was rated to 270bhp :-/ :-/ :-/

Anyway.... Chris, I'm surprised you have a problem like that. Mine runs seamlessly except for the 1st-2nd change (which was easily overcome by switching to petrol) and I'm sure Kevin's doesn't hiccup like that. I wonder if it's a limitation caused by the Vertical Torroidal Tank :-? :-? :-/ :-/

Back from WIM and very helpful they were too   :y :y :y

Seems I got lucky with the camber settings after the wishbone change .. almost spot on :) Full geometry done and a clean bill of health for the chassis alignement and other bits.

2 new tyres - they recommended Avon ZV5XL so I agreed, asked them to rebalance the 2 old ones just to make sure everything was fine ...  and thats when the bad news started ......

Off came the first rear for balancing, still has a couple of months wear I thought ... and they agreed ... so off came the second ..... "did you know you have a nail in this ?? " :( It's leaking slowly, in the shoulder, and not worth repairing ... so I said replace those tyres as well. :(

They then discover they only had the 2 Avons which are now fitted .. so they did me a deal on 2 Falken FK542 ... which I thought was very good of them.

Then the guy says ... "did you know one of your rear pads is almost nothing ???" ... so I look and decide to drive home without using the brakes if I can !!!  Go via the stealers for some new pads. Big debate over which pads I should have, and they only have the ones I think are wrong in stock anyway ... so I take them with  a phone number to call if they are wrong. (more details/questions in another thread)

So wishbones (£125), geometry + 4 new tyres (£450) plus either £20 if its the cheap pads or £50 if its the others, and the car is sitting undriveable with no pads in !!  :(

Still, it did handle far better on the way home than I ever thought, especially as I thought it handled well anyway !!! Be interesting to chuck her about a bit once the brakes are sorted .. :)

And this whole saga  started with some unusual tyre wear !!!

Glad your back to full health bar the pads. :-)

Would be interesting to have a look at those old wishbones...do you know how old they where? Did you have a look at the knuckle joint(play) and bushes splits/tears? Strange one this imho.
