I'm convinced I have a power divider on the way out, thanks to one of my other trucks and some info on this board. Just a bit of history so you all know, I own 3 Mack trucks (04-CV713 Granite, 05-CV713 Granite, 05-CX613 Vision). Current issue is with the Vision, same symtoms as on the CV713 that I had someone fix before. Also, I ran tires that were worn more on the rear drive axle than on the front - big mistake. At any rate, I'm thinking of making this repair myself. The last truck cost me $834.84 (323.00 in parts, and remainder in labor and tax). I could use the $500 or so because business is slow, which also gives us the time to do the repair. I'm no stranger to the toolbox, and would certainly have every standard tool required, as well as the talent to use them. That said, the shop that did it was reasonable, and I trust them to be fair; and will most likely have them repair this truck too. So here's my concerns and thoughts about doing ourselves: - are there special tools required - torque specs - measurements or inspections required - don't want to try to save a buck and end up causing more/bigger problems - end up not being able to finish the project - if it's complicated, I'll let somone else do it - if it's simple, I'd try it. Thanks - and great site you have here.
