I changed the syncro on mine as a precaution, and I also changed the tranny fluid, full tune up, u-joints, changed to synthetic oil, new K n N air filter, new timing chain(the cover gasket was leaking so I replaced everything) new brakes, new oil pan gasket, new wheel bearing, new starter, new lower radiator hose and a bunch of other stuff and after all that I was only out less than a thousand bucks. Point of the story is that anything that needs to be done to it is pretty cheap if you have the ability to do it yourself. A shop wanted 1500 bucks to do the timing chain and I did it in 6.5 hours and was out 75 bucks in parts. Put after market exhaust on it and pull a few more ponies out of it, worked for my truck.
