you have to get the codes read, otherwise your guessing with your wallet.
they can be purchase online, their is also a member that rents one. if you do a search you should be able to find his post.

 

Where are you located? There are some forum members, myself included, that can help you read your codes.

 

I would say bad hub(s) rovelandparts has used hubs for around $250

Check the roto flex coupling on the rear drive shaft. Rotoflex is $65 + 45-100 in labor. Or just get a new rear shaft.

Take it to a shop and have them lift it with someone in the truck, hit the gas, and see if you have any wobble... Could be a bad axle as well.

 

I replaced the rotoflex with a genuine one last week. For 250 i'd get a new hub for 350, Ill probably get a used one since i have seen a few for around 100 dollars.

I dropped by another foreign place just to ask for ****s and giggles after school and came to found they have the equipment and use it all the time. Turns out the other foreign shop lied when they told me that this shop doesn't have it.

Curiously my hub is bad, noticed it at highway speed for first time and the lights came on. When he scanned the disco it had 2 right rear codes and also said shuttle valve failure.

Wtf are the chances the shuttle valve failure occurred the same time the rear right codes came up??

time to look for a big torque wrench i guess...
