Knocking Noise @ Front Axle
32 Attachment(s)

Some days ago I repaired my front diff (new diff case). Now I have a "knock knock knock" noise when I accellerate.
The only thing I found that there is way too much play between the ring and pinion gear.
Could this cause this noise?

I only want to be sure that there isnīt something alse. I touched all suspensionparts in the front and everithing is tight.

On Wednesday Iīll adjust the play between theR&P gears and I hope that teh noise will be gone then.

Here you can see how much play there is:

Yea looks like you might need to reshim the pinion. The play should be minimal. between 20-25 inlb to rotate the pinion with it all hooked up.

Reshim the pinion? I didnīt touch it. I only installed a new ARB diff case.
IMO I should reshim the diff case. The ring gear has to come closer to the pinion.

Could that much play cause the noise I heard?

I think so that is what I meant sorry! Little pissed on my side so I am not quite focused. Yelling at people.

when you say diff case, you mean like the carrier? if so, did you reset your backlash when you did? looks like too much backlash to me.

I only changed one side of the carrier. And I thought that I donīt have to adjust the backlash after that.

what do you mean by one side of the carrier? (sorry, im not familiar with ARBs)

I replaced #19:

i would think that you would need to after that, but like i said, i've never touched an ARB before. if it started doing this after the install/repair, i would almost guarantee you need to shim it. it looks like too much backlash to me, but I'm no expert (only done a few...with help :D )
