View Full Version : I have a weird rear end...

Couldn't resist that title :D

I have a spare rolling 59 Lark frame that came with my Lark... towed it on my dolly, rear wheels down, 150 miles with no problem... parked it in my side yard...

Went to move it yesterday, and it won't roll! Here's what's weird: when I drag it one wheel will turn backwards, like when you drag an automatic in park with non-TT rear...[:0] Both drums are free, and I pulled the driveshaft.....

Haven't pulled the cover or anything yet- can anyone tell me what the heck's going on?!?

I've been around awhile, and have never seen this one before...

Wow! That is weird. I have problems similar to that when I have some
types of Chinese food.....

You might try putting the axle up on jack stands, and turn the wheels
to see what happens. It sounds like it froze in the pumpkin. Is the
driveshaft yoke turning when the wheels turn? Maybe the pinion bearing
has froze up forcing the wheels to respond like an auto in park.

like sbca96 said the pinion bearing may be froze up ,possibly caused by towing it with little or no lubricant in third member.

The pinion does turn... making this a really bizarre deal...

It is obviously possessed, quickly dig a hole and bury it in the back
yard, and never EVER speak of it again.

I think Tom's got the right idea! But seriously though, I never saw one do that either, but I am thinking what if a TT rear had a locked pinion and you tried to drag it? Would the wheels each want to go a different direction, like when you turn one on jackstands?

Can't do that, Tom- might permanently salt the earth [:0] Plus I consider it my duty to drive out any poltergeists I encounter in any Studebaker... which is the purpose of this post ;)

The only way I can think of for this to happen (wheels turn opposite directions and pinion shaft is actually turning, not just the yoke) would be for the pinion shaft to be broken or it's teeth stripped off. For the wheels to only turn opposite directions the ring gear has to be stationary. If it turns, both wheels will turn the same direction. But if the ring gear won't turn, the pinion shaft shouldn't turn either because it a direct tooth to tooth connection. If something like a broken tooth has happened, it's possible the turning ring gear kept the tooth suspended in lube and off the bottom of the housing. When stopped, the tooth sunk to the bottom where it has wedged the ring gear in place. More than one tooth would have to be broken because the hypoid design uses a spiral bevel gear design that insures several teeth are engaged at all times, so it would have to be reamed off pretty slick.

I know, it doesn't add up; I'm going to pull the cover if it ever stops raining here [}:)]

Maybe some Holy Water? Consider having a Priest present when you take
off the diff cover? Halloween IS coming up, who knows what EVIL lurks
inside that axle housing. It could make Freddy, Jason and Bill Clinton
look like Pee Wee Herman.

Finally, a month later [xx(] I've got the frame in and pulled the rear cover...

You all were on the right track... When the cover came off, all that came out was about a cup of water!!![xx(] Turns out the ring and pinion IS stuck... the spiders are turning, which of course caused the symptoms noted...

Hard to believe I towed that 156 miles at highway speeds with no problems [:0]

I've lost interest in going any further into it; I'll just go through the rear end assembly currently in the car and put it in the new frame... the other one'll be in a storage van....;)

You know, we had a full length mirror in the dressing room of our master bedroom. My wife used to say the above whilst looking at herself from time to time...
