I'm setting alignment on all four corners but I'm baffled by rear the toe adjuster. I can see the adjustment on the lower wishbone, a large thread with a narrow lock nut. Inside the wishbone cup there is smaller threaded bar with what appears to be a nylock nut. What's the purpose of this second smaller thread and nut?

Better still, what's the method for adjusting rear toe?

Not sure if this will make much sense, but here goes:

In effect the large threaded adjuster doesn't move (as in it doesn't move towards or away from the chassis). As you turn the large adjuster the thread on the inside of the wishbone moves the wishbone in or out. Thus setting toe. Once the wishbone is in the correct poistion for the toe you want, the thin nut is screwed down, clamping the wishbone in place on the threaded adjuster. The small nut inside the wishbone clamps the entire assembly to the toe adjuster which is the part bolted to the chassis.

Sorry if that doesn't make too much sense, but its easier to describe with photos. If I can access them here at work I'll post these up as well.

They certainly do phillpot

Loosen large locknut and small nylock nut. Then adjust toe by rotating large threaded tube


eta ...and thanks Kris for your explanation

They are usually seized solid. My TVR guy's price for a 4 wheel computerised geo is quoted at £75 or £90 (can't remember which is) plus VAT and freeing off the rear toe adjusters. smash

You do need to get it on a 4 wheel set up so you get the trust angle correct smile

I've assumed the thrust angle is zero with respect to the centre line. Is this not right?

correct... the THRUST angle is zero... but its a sod to get right working back to front then front to back.. I tried for ages but could not get it correct... 30 mins on a Hunter, problem solved wink
