The answer depends largely upon what is failing or has failed. If you have a major failure it is possible for the unit to lock up. If not, it will continue to worsen till if completely fails...where that will happen is just a guess.
With a large heavy vehicle, stress on the diff is higher than with a passenger car, limiting how far a bad unit will go. If you don't know what is failing, it could be a wheel (axle) bearing...that is also a problem.
If absolutely no help is available, make sure there is lube in the unit. If no lube is available, use engine oil...some oil is better than none, even if it's the wrong kind.
Best of luck !!!

Potential driving hazzard would be everything coming apart inside the housing and jamming up solid and of course, ultimately, breakage....then you're towing it back or at least to a shop....

Probably broke your U-Joints on your driveshaft, preventing the rear wheels from turning. Your driveshaft might have disengaged from your differential too. check underneath concentrating on the driveshaft and differential

if the diff is not leaking oil there should be no reason to be low. If you hear a noise in neutral with the truck not moving, its not in the rear end. it may be the trans or transfer case.

All cars do this a little because of the tranny tail bushing, drive shaft U joints, differential input bushing, and differential ring and pinion. But 4WD does it more because of the transfer box as well.
Check the differential fluid level, twist the drive shaft looking for slop, but also push up and down where the shaft goes into the tranny and the differential.

1987 dokota appears to go in four wheel drive but all wheels do not pull or move when stuck in snow or mud.


Technically you do not have 4 wheel drive, you have two wheel drive (possibly three-wheel drive). When you engage 4WD you direct power to the front and rear differentials. The front differential is an open style which means that only one wheel will drive, and the rear differential is likely the same type which means that you will only have two wheels driving the vehicle (one front, one rear). If the rear differential is a "posi-trac" or "limited-slip", then both axles should lock and drive the vehicle (hence, three-wheel drive), but this style differential is not as common as it once was.

I own an 02' Jeep Liberty. It is either the differential, or the drive shaft.
Is it the front or rear driveshaft? Does the Jeep drive? If the driveshaft
was bad, it wouldn't move, so I'm assuming he's screwing you,since driveshafts don't smoke.LOL. If your front or rearend lube has come all
out or very low, you could get smoking from the diffs,especially if the fluid hit's your exhaust. look under the jeep, to see if any fluid is leaking
from the front or rear driveshafts?good luck.

Where do I find the gear ratio for the rear diffI I have a 2000 blazer ls 4 door 4x4


Lower down this page is a chart with RPO codes, which can potentially be found inside the glove box...
The codes pertain to the transfer case, the front differential, and the rear differential, so it may take a bit of snooping.

However, if you were merely looking for the driving-gear-ratios, here's a page containing that kind of information for a 2000 4wd ls blazer:

if this is a 5 speed manual transmission...all you need to do before putting your jeep into reverese is puting it into first gear and then shifting it to reverse to avoid any grinding or problems shifting into reverse...this isn't a problem just a poor jeep design by not installing an extra gear to eliminate this grinding or shifting problem
