This morning I got into my truck and while the truck was cold started to back up and noticed it being stubborn and resilent to back up, rear end shaking and a pulling feeling like it didnt want to back up. I put my head down and looked at the rear end while backing up and noticed the rear end vibrates and truck tends to shake. I have a full spool in the rear but it just started doing this

 

Also i might add it just started doing this

 

are you sure its not the tranny thats shakin

 

this happens with my lockright when making low speed tight turns sometimes. I'm pretty sure its just my motor/tranny mounts being worn out. I assume its because the engine doesn't have enough power to break the inside tire free and instead it twists the engine/tranny.

 

great

 

can i just tighten the mounts ? think that would fix it?

 

probably not..

if your mounts are shot to the point of not doing their job its time to replace them. $.02

 

which mounts are we talking about? the case mounts or the drive shaft mount to the 3rd

 

i would check every mount you have.. I don't know if the mounts are even the problem. But give them a good look over, grease your drivlines/ujoints and see if you find anything/

 

If its lugging like its binding/unbinding then its probably motor/tranny mounts.

If its vibration, could be the driveshaft, but it would do the same going forward also.

 

yeah it only does it in reverse at low rpms, so tighten down the motor mounts and tranny mounts?

 

You can't tighten down the motor or tranny mounts, they're two plates with rubber in the middle. Once they start to tear there's no fixing them.

 

niccantdecide theres no rubber inbetween the plates, i have 1 bolt right now holding the plates together, pretty sure if i bought 4 more bolts i might have a chance of fixing the problem

 

Replace the mounts, its not like they are that expensive...
