my trac lock unit is shot...i got the one wheel blues my question is should i just get new clutches for the track lok unit or should i do all the bearings and all that good stuff. also if theres a part number/where to get a good heavy duty rebuild kit let me know...im also going to put some 3.73s in to replace the stock 2.73 highway cruisers..also have 135k on the car too
