Pinion and diff carrier adjustment shims...

[rokdaddy]

I'm about to install front and rear lockers and regear while I'm in there. I'm looking at the OE shim selection and it looks like I'll have to spend ~$300 in order to get one of each size for both axles.

There must be alternatives to the OE shims, anyone know of another brand/type that will work? Also, are setup bearings availible for our diffs? Seems like it will be a PITA to have to install and remove bearing races every time I try a different shim size.

The problem you're going to face is not having a snorkel

this is all to get with in spec for backlash right?

Yeah and the bearing preload.


No shims needed for the rear axle. Just the front. Wish I could aid but I bought my locker used and it came with the proper shims. I would imagine if you took a shim to the auto parts store they could match it up.

Rear required a special nut tool. Some people make them from scrap. I bought the rugged rocks tool.

yes, the way the the rear is adjusted is sooooooooooo much better then throwing shims.

I would very much agree. I've had issues with the bearings lasting in the front axle. I don't know if its the heft of the locker carrier or what. Seems every year I replace the bearings. Seems as though its adjusted properly meets all nissan specs. I'm not the only one either.



Also don't forget to order the Toyota V6 pickup bearings for the rear axle. They have a slightly larger internal radius which is required with the locker.

The carrier adjusters do make things easier but unless you're really lucky, you still need to re-shim the pinion depth.

True dat... that's an easy one to miss. Terra swiped my first set of retrofit Timkens (she bought me a replacement set) to complete her rear locker install.

did you do a whole front diff overhual? if so, did you get the crush sleeve for the pinon gear in right the first time? or are you shimming then crush sleeve?

I've been waiting 'till winter to do my front and rear diff locker/re-gear/rebuilds; we have been using the X this summer to scout log cabin building properties. I work slowly and carefully and I expect that the X will be out of service for about a month or so.

The rear diff setup procedure calls for adjustment using both the carrier adjusters and shim adjustment for the pinion. The front diff procedure calls for carrier shim adjustment and pinion shim adjustment. The front diff does have a spacer sleeve that resembles a crush sleeve but the pinion depth is achieved by swapping out adjustment shims.

For now, I'm trusting the FSM and internet research but I'll do a detailed write up once I get in there.
