The other day while working on my 68 convertible I had a problem w/ my 68 custom that was completely unexpected. Currently the engine, transmission,are out of the car and the front clip is is off of the car I’m soaking the body body bushings in PB blaster to hopefully not snap the bolts . I jacked up the rear of the car by the center section to get better access to the rear ones . I then lowered the car & went to push the car forward into the garage . The car was locked tightly in position as if the brakes were being applied. I was at a loss and jacked up each wheel individually making sure each was moving free and clear. The driver’s side rear was frozen. I then pulled the wheel off expecting the drum brakes to be froze but the drum came off easily. When car was up in the air I was able to spin the wheel with considerable effort . Lowered it down - car was still frozen. Next day brought a friend over to look at it. Jacked up the car to show wheel was still immobilized. This time when I lowered the car down magically the wheel spun freely . As I said this is a 8.2 NON posi original rear with no issues previously. Any and all opinions appreciated .
I know this may sound like a dumb question, but was anything connected to or contacting the pinion yoke?
I know that’s the only sure way- I’m doing a few big upgrades on the car and the rear is midway on the list . The car will not be moving off property for a few month but will be necessary to push in and out of the garage regularly. A set of dolly’s my be in my future.
Dolly's are great! I moved and now have a shop/garage 30x40, so I put the cars on skates, crank up some good dance music, get nekkid and push my cars around for giggles!!! OK, so maybe I'm fibbing about some of that... I don't have a radio.
HAve to PULL the cover. How long has this car been sitting? Might have a piece of debris that got edged in the spider or the spider gear shaft has fused to the spider gear in spot and is starting to weld it self to the cross shaft...?? AGAIN opening and inspecting will be the only sure way to get the answer. JIm JD Race
Dollys are great - but - check out the casters. Some are metal, some are plastic, some work, most don't. When you put the weight of a car on them they won't roll. The videos with one guy spinning the car on an asphalt driveway are syfi. Get some good quality casters. I up'd mine to colson 3 inch.
Sitting 5 months; however car pushed in and out of garage on to driveway, 12’ to 15’ , at least 3- 4 times a week with no problems . I realize opening up the unit is the only way to be sure . Thanks Jim
I've got a buddy having a similar issue. I'd be interested in hearing what you find. I'll report back on my thread if we get his figured out.
I was going to tag you on here having read your very similar thread (thought it was on one of your cars). How strange to have 2 nearly identical issues.
What undue pressure can happen on the rear end when you jack it up on the pumpkin? Small cracks on the iron housing or a axle tube or the pumpkin slightly bending and doing some damage or weird pressure on the moving internals etc.?
Why you Why do you think they call machined (carved) pumkins "Jack-o-Lanterns"? It's fine to use a good floor jack centered (and I use a thick piece of leather as a pad) to lift the car with the diff housing. Manufactures will tell you not to due to safety/liability issues.
