Cheers chaps - what's the reason for them sheering though - I can only think it's a direct hit from a rock or similar or seized in and sheering when being undone?

Cheers

Either impact or fatigue, hell of alot of stress goes through them, especially off road.

you need a couple of good quality 12mm bits i think i used piranha. and some kind of coolant / cutting paste. a drill with some guts makes it easier too. nice and slow and let the drill and bit do the work . took me about 20 minutes per side. careful breaking through the other side as the bit may nip up and snap. i think they shear on a lifted jimny ( non caster corrected) as the shock sits at such a bad angle over the bolt putting loads of pressure on one area. even standard ones i have seen are at an angle.

standard jimny - for now

Thanks again chaps. I've been playing with brake pipes and diff breathers so haven't done anything yet and was considering whether I shall do so or not, using the info you have all supplied to assist in making a decision.

Robs5230, you make interesting points about fatigue and angles.

Mine have been abused in the past but not failed once. This was with no castor correction with a 3" lift too.

Now I have Castor Correction and new bolts. We shall see. It is certainly easier to do it now than when a bolt is sheared off inside!

I grease them with waterproof grease on the bolt threads regularly and carry spare bolts, should one come out, but do them up with my electric impact gun, so they are unlikely to do so and never have.

I shall have a think!

Nope! It hurts and I've just had a stroke! Not another one, the original one!
