I recently had a grizzly locker installed with chromoly shafts in my rear. I got the job done by a really great shop and I am confident in the owners work, but I am hearing a strange noise since.

I know the locker makes some noise when turning and engaging but when I put the jeep in reverse and let off the clutch it makes a very loud squeaking/metal on metal noise.

Is this normal for a grizzly locker or something I should be worried about? I'm betting it is something I should probably be worried about...

 

they can be loud, and may get a tad quieter after the break in time.

 

I've never heard a locker make a squeak or metal on metal noise,its usually and bang or series of muffled clicks...then the bang. I would check rear brakes,backing plates,etc.

 

That's what I thought too. I guess it is just coincidence that the noise started when I installed the locker

 

its ONLY in reverse? Not when turning in say a u turn? Are you turning in reverse when it happens or is it always?

 

Only I'm reverse. And keep in mind I am not breaking in reverse. I drive a six speed, if I keep the clutch fully engaged there is no noise but as soon as I let it out a but I hear the noise. I havnt tried full clutch out and foot on gas in reverse because I haven't been in a situation I've reversed that much lol but that's the circumstance.

It happens when I am going straight in reverse and when I am turning.

I haven't heard the noise in a u turn. Only noise I hear while turning when going forward is that clunk noise from the locker which I know is normal. This is a completely different noise

 

The only other thing I've done recently is had a tire rotation...

 

gotcha, my bad i was assuming you were hearing the locker clunk noise.

 

Anyone else have suggestions ?

 

Check the ebrake internals. One of the springs may be off and the pads dragging/binding. When backing up and the noise can be heard,pull up on the e brake slowly to see if the noise changes.
