Hi ang94541
I am glad I am not the only one sitting with this problem. My car doesn't see the freeway that often as it is only driven over weekends. This is the reason why I can't justify the price it is going to cost to get a 5 speed box or even repair this problem on the 4 speed. We have a freeway speed of 120km/h here in South Africa but I can take it max 110km/h and then I can feel the vibration starting to come in.

Another guy here at work told me exactly the same idea you have. Making a tool whereby you can get the old bush out and then pressing in the new one. He also suggested to use a flat piece of wood when hammering in the new bush not to damage it. The one gearbox shop I phoned recommended that I do not follow this procedure as it can damage the bush. Hell, the price they are asking to pull the gearbox, fix the problem, new gearbox oil and put it back in I am definitely not going to use them.Especially with the possibility of damaging my GX manifold when removing the exhaust from the manifold to get space for gearbox removal.

If you really struggle with the bush on your side, I can get one for you here brand new and we can mail it by sea to bring postage down to a very low price. Let me know.
