I'm a nub to this forum, so please bear with. I just got part of my steering column replaced, drove off the lot yesterday, 15 minutes later heard a grinding from the passenger side. Got home, checked pads and rotors, looked worn, but still good. Drove a bit more. The grinding will stop in 4wd, begin in 2wd. I have it down to the hub, but here's the problems:
1. Does anyone think a vacuum line could have been damaged during the steering repair,
2. If it is the hub, can I put manual lockouts? Called a few placed and they seemed to think I couldn't. Problem is, the auto locking cost too much.

Thanks

 

I can't remember if the IWE solenoid causes this

 

Its the iwe hub or actuator......

No manual hubs are available for these trucks.....

OP, to Q#1, possibly. That would be the cheapest and easiest fix.

 

Thanks. Nice write up too! Will check this evening after work and let you all know whats up!

 

Thanks again ya'll. The vacuum diagram helped a lot. Traced the lines and found that the shop must have disconnected a vacuum line. Put back on, runs fine. Thanks for the free fix!
