I am looking at a 89 GMC Heavy half ton(six lugger with a 14SF rear).... The front needs bearings where the CV shaft enter the carrier housing and a CV boot. The truck has about 140K on it.. Are SAS(Straight Axle Swaps) that hard? Anyone do one on a similar truck and can offer advise and any problems you ran inot? I would put a D44 from a Ford under it for now... I know ORU makes a kit for this, but I dont want to spend the money and I bet they want a pretty penny for it.. Any advise???? BTW, it has a lift on it now.. It is either a Superlift kit or an Explorer.... About 4-6".. Thanks!
