    I have a 65 panel. My mechanic says the differential is making noise. He suspects a bearing is wearing out. Any advice on what to expect? If we're going to open up the rear end is it feasable to change gears for better road speed?

    We opened up the rear end this weekend. It's a 3.73 rear end. All the bearings are worn. The pinion has some in and out movement. The mechanic says everything looks original, shocks, springs, cover gasket. Where do I get repair parts? Would somebody on here, who knows about this stuff be willing to talk on the phone with my mechamic?

    It sounds like you have a 12 bolt rear axle ?? You can get a kit fairly reasonable through Summit or someplace like that, What you will need for axle bearings is going to depend on the condition of the axles at the wear area. If it hasnt been changed out the kit you need will be for the car but the only difference is the axle bearings, trucks are larger, if you need to use repair bearings for the axle then that wont make a difference.
    This is the repair bearing you may need for the outer axle.

    To use the repair bearing you will need to smooth out the ridge at the hub flange.

    I don't know that he is talking about the the axle bearings,,,,,,if the pinion is loose, it has 2 bearings on it and a crush sleeve on it to keep the bearings tight,,,,,,,,then the carrier assembly for the ring gear has 2 more bearings on it,,,,and there are those 2 bearings in the ends of the tubes whose job is to eat up our axles. I would say Napa has all 6 bearings and the crush sleeve,,,,,,

    The 3:36 is the more common rear end,,,,,,,the 3:73 has more power for towing but the engine has to turn faster, which makes more noise and uses more gas than the 3:36. VanAgain has that rear end in his 65 and we could not find wheel cylinders for that rear end, so I gave him 3:36 backing plates and wheel cylinders to put on it. So how far have you torn down the rear end???? are the axles out???? If the section right behind the flange does not look like a shiny spark plug socket and has grooves cut in it, that will make a bunch of noise while driving,,,,,that is the most common source of rear end noise,,,,,then the ring and pinion howl when they are out of adjustment,,,,,,and then you got the 2 pinion and side gear bearings,,,,,so you need to take it apart to see what you find,,,,,,,,but I think you should find a 3:36 rear end......

    Indiscribable improvement. A completely different driving experience. I'm gonna take it out on the highway tomorrow. Thanks for all the advise.

    Hey Richie Rich,

    This is an old post, but I'm left wondering... what did you end up doing to the rear end that resulted in this vast improvement?

    I'll be crossing this bridge soon, with a seemingly original rear end in my '64 g10.
