d-30 spider gear thrust washers

I posted this in the YJ section, but thought it would get more attention here as it should apply to all dana 30s.

I installed a lockright in my YJ and it was unlocking and making a bunch of noise on the trail. I tore it back down tonight and read the instructions . I found that I was supposed to have .152 between the halves and I have 175~. My shims measure .030 so .040 (.010 per side =.020, .175-.020=.155) should get me to .155 which is nearly perfect. Where can I buy these things? After much internet searching, I'm not finding them.

I just did a google search for "dana 30 thrust washer." Came up with numerous sites that have them.

I found lots of sites with thrust washers, just none that listed the thicknesses.

I called Richmond Gear tech support today and explained the situation. He told me that all the lockers were machined to VERY close tolerances and the problem must be in my carrier. I picked up another carrier today and reinstalled the locker....exactly the same. He also told me that the inside width from thrust surface to thrust surface should be 2.751. I measured both carriers that I have and they are ~2.753. A little large, but not .020 large. I am surfing now to get the correct dimensions of a lockright locker. I'll post up what I find.

I am having the same problem. I have been through two lockers in my XJ and they both did the same thing. With new thrust washers I have .178.. Did you find a solution?

Thread Resurrection...having the same issue with my Lock Right. My gap was about .190" - the specified range is .145 to .170". This was with the used thrust washers, which both measured .027" each. Anyone ever come up with a good solution?

I did call Powertrax (Richmond) tech support when I discovered that my locker wasn't ratcheting. They weren't horribly helpful other than to give me the gap dimensions. I tried to call them today, but no one answered - probably closed for the holidays.

Following up to my own post...I ordered a new set of thrust washers from East Coat Gear Supply $3 for the pair - I got great support from ECGS. They measured the new washers at .030" each. So, I think I'll use the two new thrust washers and one of the old washers, which should give me a near perfect .157" gap. I also ordered new Ring Gear bolts from ECGS, since you aren't supposed to reuse them.

I'll followup again after I get it installed.

Did you ever get this resolved?
I was thinking abut your solution. I'm in a similar boat. I have both my original .0275 washers and the new .0270 washers with the kit. Doubled washers don't work for me because the decreased clearance wont allow the spacers to clear the center pin. Seems the proper solution is to get the .035" or .040" thrust washer.

Yes, adding an extra thrust washer solved it for me.
