im not too much into writing on forums, so ill make this quick and easy.
last week i bought a non running 91' exceed, with the hope to fix it (and keep).
it was in a driveway off to the side pretty far so we got the tow operator to move it out first then hook it up, but just as he goes to pull it, we realize one tire is not moving, while the other tire is spinning in reverse, so we had to dolly it, i know mechanics pretty well but even my friends family and other mechanics cant answer why it does that.
is this normal jap technology or did i buy a van with a F'ed up rear end or even worse, the transmission.
and in that case for the motor, the guy who sold it to me said that the timing belt had fallen off and there was a chance there was damage, people have been telling me its doubtful its anything more than bent valves.
other than those 2 things, the van is in great shape, 100,000 km, no burns or smoke damage or anything, sooo
what do you guys think?

If you can be a bit more clear on the rear end that would be good.

It's most likely an open diff so one if you spin one tire, the other will turn in the opposite direction (when both are off the ground).

If one is not moving/dragging on the ground, a seized caliper is most likely the culprit.

As for the timing belt falling off, you can go from very lucky (not damage much) to very unlucky and need a new engine. It's an interference engine, so it can be catastrophic inside. The damage can be extensive down to the block or just limited to the head. Either way, you'll need to pull the head to really know for sure. If someone told you that it's nothing, then they may be out to lunch. Since the summer, there's be almost a dozen blown motors because of the timing belt skipping/breaking/pulley/tensioner breaking. It's 99% because of lack of maintenance and/or improper installation. Hopefully, you're one of the lucky one's.

Since you bought the van with the intention of fixing it, I'm assuming you're a mechanic, in which case it's straight forward to pull the head, get it tested/do leak down test.

The search button is pretty good and will turn up these if you enter head, timing belt, damage, or anything like that in the search bar.

im not sure what it has for a rear end, the guy i got it from didnt know too much about it.
but regardless, i mean one tires dragging, while the other tire is spinning against the direction it was traveling, so even now, its in my backyard, and theres no way i can move it. (a major problem)
being a 20 year old vehicle as well i dont want to start dragging it around with my quad or something if one wheel is spinning the opposite direction,

and i kinda figured as much for the motor, guess ill have to wait for the next warm day and get out there and starting pulling the head off

Silly question but is it an auto or 5spd and was it in neutral with the parking brake on ?

if the tranny is literally done and locked up, your rear end will still move. open diff will let you turn the wheels.

Possible that the ebrake is yanking on the one tire or the caliper is seized and the tire's locked up.

its a 5spd, and i was almost 100% sure it was in neutral, handbrake was "off" but the van had been sitting for a year or 2. so anything can happen when a vans sitting that long.
and like i said, if i drag it north, one of the tires is not into that, so it goes south.
i got the basics on how the whole differential and transmission shit and how they work together, but this has me totally stumped.

Rear ends in North American and Japanese cars are the same design. I would pull the brake drums off both sides and disconnect the drive shaft. Most likely the drum is seized from sitting (hit drum with hammer helps) or the brake cable seized from sitting. It also sounds like it might be in 4 wheel drive.

Diesels have 20:1 compression and are interference motors meaning piston will hit the valves if the timing belt fails. Pull the head damage depends on depending on RPM, load, and luck.

X2.
We went to CCautos yesterday to meet deadline for 2 cylinder heads delivery.
Heavy snow kept me on the road almost 3 hours between Nanaimo and Coombs.
Anyway my record shows almost 20 4D56 heads have been sold since last summer.
Preventative maintenance with good quality parts is the key for the small diesel engine.

well regardless im going to start pulling things apart hopefully this weekend, but i still dont get why if you pull it one way, why one of the tires would drag in the opposite direction, even if it was in 4WD.
but when i find out ill let you guys know i suppose

If the wheel was unloaded, its the natural action of an open diff I think, either way I dont think anything is wrong, the laws of physics dont change because its an import or because its been laid up

no, i mean if i drag the van forward on pavement, one wheel is not moving, while the other one is spinning in reverse.
so if i did happen to tow it like that on the highway, one wheel would have been dragging, while the other wheel would have been going the same speed as us, but in reverse.
and yes, it sounds like BS, but im totally not lying, one wheel dragging with the other spinning in reverse

Take it out of 4 wheel drive so the turning front wheels are not trying to turn a rear axle with a frozen brake.

Drive shaft is turning, 1 wheel is locked, the differential transfers the power to the other wheel and due to design turns the wheel backwards.

Seems simple enough to me.
