Seems like a rebuild unit would cost around $500.00 when a rebuild kit costs about $100.00. I have two 3rd members, one installed and one in the shed so for me the rebuild kit would be best. If you buy a used one for a swap and just install it you are taking a chance that it is in worse condition than the one you currently have installed. To me 'swapping' without rebuild is a mistake and $500.00 is too much for something I can do myself.

I have found a few 'how tos' on the net, none of them have mentioned special tools but if some are needed I can either make them, buy them or make do without them if possible.

I may be different but I do get enjoyment out of working on my truck. I also know when I am finished with a repair that it is better than any shop would do.
