Just finished my 4.8 chevy conversion and she runs great in 2 wheel drive.


When I set the lockers and shift into 4 wheel drive above 25 mph it sets up a vibration and knocking noise in the tunnel area. When I discounted the lockers the vibration goes away. The following is the build information.


Rough Country 6.5" lift, 89 Jeep wagoner front diff. TNT truss, front drive shaft is custom and balanced.


Any thought or ideas would be very appreciated.

I'm short on answers with the information given, but damn that's a nice wagon for sure!

Which TC you running on that and which lockers you running

ocs1667

The TC is the Jeep NP231 and the lockers are warn.

What the hell is a warn locker?

I'm thinking Warn locking hubs, with his Waggy D44? My best guess anyways. Nice looking XJ though, I like the colour gradient from front to back.

Edit: Also, just look at the picture. They're there. I didn't look hard enough the first time.

Probably warn locking hubs. My guess

Locking hubs is a good place to start. Specially if the hubs weren't serviced for a while

Warn used to make lockers, don't know if they still do. They were expensive so production probably ceased.

The Warn lockers are brand new, my guess and I didn't mention it is the angle between the TC and front diff., and maybe the front drive shaft u-joints? I planed on disconnecting the drive shaft and placing it in 4 wheel drive. If the vibrations still exist then my thinking is the TC. If not, then I will lock the Lockers. If no vibrations, it is the angle and or the angle and u-joints. I didn't speak of this as I was looking for other points of view.










I replaced the original fenders with 2001 fenders to get a better fit with the front bumper. It was bought out of Craig's List and was used for a photo shoot in 2001. It is aluminum and weighs about 75# max. I had it powder coated black.

Do have an idea of what your caster is at? That could easily be the problem, if the u-joints are still in good shape.

You probably have warn lock out hubs, different than a locker.

Ok, OP take some pics of your front and rear DS angles at th TC and at the pinion. Take from the side view
