How do I check to find out if my rearend in my truck is shot or if I have a broken axel?

Question

When I shift the truck into gear I here a clunk, the driveshat jerks a little but the truck won't move. Even in park the truck will move, making me think that something may be wrong with the reaend or the axels. I have a positraction rearend if that tells you anything. Thanks, Jess

Answer 1

i own a repair shop,and believe me you,d know if you had a broken axle it it,,it make one major bad sound,,like a hammering sound in it,,the only thing you can do is tear it down to be sure about it,,that's the only way to find out for sure on this one i have done a lot of them,and if you,ll tear in to it,,you,ll soon know ,or have it done,,good luck hope this help,s.

Answer 2

Depends on what type of truck you have but on Chevy trucks the rear is prone to problems. I have seen the same problem you are having and the solution was a new ring and gear with a new pinion. If the pinion breaks or if pieces break off then the drive shaft will just turn around in circles and the wheels wil not turn. It's slightly difficult to replace and requires air tools. You might want to replace the rear with a used model from salvage.

Answer 3

With the parking brake off.
Jack the trucks rear wheels off the ground.
Pull on the wheels.
If they slide out, you have a broken axle.
If they don't, you have a bad ring or pinion.

Answer 4

Jack the rear end completely off the ground, support the axle with stands, Be extremely careful, use wheel blocks on the front wheels, in front and behind, put vehicle in nuetral, try to free wheel the rear wheels, if they rotate, then its most likely the transmission.

Answer 6

you can jackup your car or truck's back end and pull on wheel outwards if it moves your axle is broken is one way, but it sounds like maybe your problem is transmission

Answer 7

(You mentioned that if you put the truck in gear the driveshaft jerks little.)
If the driveshaft doesn’t turn it means you have trouble with your trany.
