Re: Late type Front Suspension
Hi Barry,
Problem 1 The pin should drive out fairly easily. However, if you have a distance tube between the two lower bushes, this rusts onto the pin and stops it coming out. I assume you are replacing the rubber bushes, so some degree of cutting and jiggling will be needed to get the pin out. You may have to buy a new pin! My advice on replacement bushes for the bottom of the swivel pin is not to use the rubber ones offered by our spares folks. In my experience, they don't last more than a year and are pretty hopeless. I have fitted polythene ones, intended for a MGB, with excellent results. They don't go soft and split like the rubber ones and mine are as good as new after 5 years!
Problem 2 Yes, you do have to split the yoke. The outer bushes should come away with the halves of the yoke. However, I have found, like you, that the inner bushes get stuck on the pin adjacent to the body mounting. This long pin will not come free from the mounting. Don't try driving it out! You will need to carefully cut the worn inner bushes away from the long pin and replace. Be careful not to damage the long pin or the threads on the ends of the pin. When replacing the nuts on the end of the pin, I use some copper grease here, as the threads are exposed and usually dry and rusty!
Hope this is useful,
All the best,
David

Re: Late type Front Suspension
Hi Barry,
No need to remove the top wishbone(s), unless you want to replace their inner bushes. In my experience, although these spread and fray around the edges, they're usually quite serviceable.
To release the swivel pin yoke, take out the wishbone clamping bolt and undo the two swivel yoke nuts. Now take a very sturdy screwdriver, or a small crowbar, and insert it between the wishbone halves. 'Persuade' one of the wishbone halves past the end of the pin. It all feels a bit brutal, but I've done this many times without a problem. Once one of the wishbone halves has been released, it's quite easy to release the otherone by driving out the pin. Replacemment is the opposite of the above. Have fun, but watch your fingers!
