1997 Chevy 1500 4x4 Diesel Front End Noise Sign In

I have a thumping or banging noise on my front end and I have had numerous front end parts put in including new shocks, ball joints. My garage put in new stablizer bolts, but the problem persists. Could it be the drive axle? I've experienced some problems putting it into 4 wheel drive and taking it out again. It made a grinding type noise.

Have you checked the fluid level in the diff? Also not a bad idea to pull a sample off the drain so you can look for metal in it.

Your actuator motor in the axle could possibly be acting up and could give you a grinding noise if it is binding as it engages and disengages.

Need to get this in the air and look closely at all front end parts. Sway bar links are new, but what shape are the frame mount bushings it? What about the steering linkage and control arm bushings?

Does it make this noise only in four wheel drive or two?

I just filled up the fluid in the diff, but have not checked for metal in the existing fluid. The actuator motor was replaced 7 years ago. The banging is consistent over even slightly rough roads, but does not present when the road is smooth.
