My thanks to grumpy and aussietrev for your rapid responses. I disconnected the steering crank ends of the two tie rods and the squeak ceased. Operating both the steering wheel and the king pins produces no noise and they move quite freely. The inner tie rod end of the LH tie rod appears seized, and is difficult to move by hand. Problem solved, I think. OK. Should tie rod ends be replaced in pairs/should I replace all the tie rod ends in the system/or what? From your reply, I will be off to buy some tie rod end/s it seems. Many thanks for your help. Regards, mustang
