Great car!!! I had a 68 Super Bee, but had to sell it. Not a happy day.
As far as the differential, are the carrier bearings in good condition? Is there any noise when the wheels turn in the air. I'm thinking one of the axles is getting on a bind.
Let me know.
Thanks ive had it for 30 years it was my first car bought it when i was 16 used at a Honda dealership for 1800.00 some poor guys wife made him trade it in on a honda . it was a 340 car back then though ....actually i have 2 sets of axles for it.1 set has the stock bearings and adjusters and the other has the green roller bearing upgrade. i first thought the green bearings caused the binding so i switched out those for the stock ones and same thing.i guess i didnt hear much noise but wasnt listening to hard cause of the loud exhaust but i can run out and give it a listen when in air. it does make a loud almost whinning noise when its on ground and try going forward at first i thought it was the tranny pump making it trying to push the car but its the rear end .i also thoght it was just the 1 suregrip doing it and tried the other but it did same thing.
Since it will back up, and please I'm picturing this in my head, check to make sure the spider retainer (steel shafts) are properly in place.
Ok i just had it in air again and ran it in forward through all the gears and in reverse. i didnt hear any strange noises or anything from rear end . i am using the suregrip with the 4.56 gears and its in a 489 casting carrier. i am using the axels with the stock type bearings and adjusters . can this be caused by haveing the axle adjusted to tight ? i went by the book with .018 endplay .
No, if you have them too tight, the bearings will go bad but not stop it. Sorry it took a while to get back with you. Yahoo mail was out of service yesterday and I didn't receive any emails.
