Hi everyone,
I hope somebody can help with this, but I seem to have a problem with the diff out of my '72. The trans is out of the car so I can turn the axle shaft flanges by hand and they're as smooth as can be, but when I turn one flange and hold the other flange steady, it feels "rough" and sort of makes a "grumbling" noise. Any ideas what that might be, please? Thanks. |

Why is it out of the car? Was there a problem when it was in the car?
If I understand your post it’s running smooth when you rotate both axles simultaneously, the same amount of rotation on each axle. Then when you hold one axle fixed but rotate the other it’s feels and sounds sounds grumbly? Did it make any noise in the car when making very tight turns? |

Hi Super, The trans is out of the car as I've just replaced 1st/2nd/3rd synchros and dog teeth as - typically for a teener - the shift in those gears was diabolical! I sloshed about a cupful of 90 Gear oil into her to keep things oiled, as the car's waiting for paint and I don't know when she'll be back together. I'm trying to post a movie clip illustrating what the problem is, but my cinematographer isn't on form these days! Please watch this space. |
