Pressing bushes into wishbones

The next part of the build we wanted to crack on with was the rear. We already had the diff in didn't see why not we couldn't get the rear wishbones in place. However before we could fit them we had to push the plastic bushes into the wishbone ends.

Tools you may need for this job;

A powerful cordless or corded drill
A bench vice
Sanding drill attachments
Copper grease
Bush
Craft knife
Electric sanding machine

The first job is to sand all of the powder coat out of the wishbone ends. We clamped the wishbone n a vice and used an electric corded drill and several attachments to get it all out. We started with a very corse attachment and slowly progressed to a finer one and finally a round sandpaper piece.

Once there was no more black powder coat in the holes we got the bushes ready for pressing into the ends. Both the bushes and wishbone ends where covered in copper grease to allow for them to be pushed into the ends with ease. They were then held in the vice with two pieces of wood and clamped up. Once half way home we found that excess plastic built up on the edge of the hole. We used a craft knife to cut this off before continuing pushing them together.

Before they where pushed all the way in we used the metal feral to make sure the bushes could not be pushed beyond the correct amount therefore avoiding the plastic to warp. The feral's had thier sharp edges filed down on the sanding machine before being lubed up and slotted into the hole.

Now we could tighten it up in the vice as hard as we could. Once in place we cut any excess plastic off and wiped any excess copper grease off the outside.

We applied this same technique to all of the 14 rear wishbone holes. It took us about 10 hours to complete this process, and the vice leaver gives you a good gym workout!
