Re: Dana 44 4.09 ring gear thickness
Hi Bill,
Well, I guess I can only hope that the Tru-Lok is sufficiently
engineered to withstand the thicker ring gear. This article:
http://www.fourwheeler.com/featuredvehicles/77698/
quotes Jeep engineer Jim Repp as saying that the Tochigi Fuji Sanjyo
Tru-Lok was chosen for the Rubicon "because they were the only ones we
couldn’t break".
It does get worse though. I just got off the phone with Randy's R&P to
get a quote on aftermarket thick gears. It seems the Tru-Lok uses
smaller diameter ring gear bolts than what are found on a standard Dana
44 carrier. Sounds like another weak point.
Unfortunately for me, the aftermarket thick gears are threaded for the
standard size bolts and require bolt thread adapters to fit the smaller
Tru-Lok bolts. Grief. They do supply a thick 4.88 gear that is threaded
for Rubicon bolts, but their thick 4.09 and 4.55 gears are not.
I'll avoid the aftermarkets and look for original Rubicon gears.

Hi Steve,
I still haven't found where you think Tochigi Fuji Sangyo uses the
wrong size carrier.

Re: Dana 44 4.09 ring gear thickness
Hi Bill,
This link from an earlier post on this thread states pretty clearly that
the Rubicon diff is sized 3.73 & down:
http://www.ring-pinion.com/about/abo...page=yukondana
Can't find any official documentation. Rubi owners do mention it:
http://tinyurl.com/yux58
http://tinyurl.com/3ab3h
http://tinyurl.com/2374s
http://home.earthlink.net/~lmats/
I should correct a statement I made in my last post regarding bolt
thickness. When I said the Tru-Lok needs thinner ring gear bolts, I got
it backwards. It actually needs thicker bolts. I hadn't noticed til I
checked right now, but the bolt holes on the flange of my Tru-Lok are
wider than those on my stock open carrier. So, the adapters (spacers)
that the R&P vendor told me about are for the flange holes, not the bolt
threads in the ring gear.

I should correct a statement I made in my last post regarding bolt
thickness. When I said the Tru-Lok needs thinner ring gear bolts, I got
it backwards. It actually needs thicker bolts. I hadn't noticed til I
checked right now, but the bolt holes on the flange of my Tru-Lok are
wider than those on my stock open carrier. So, the adapters (spacers)
that the R&P vendor told me about are for the flange holes, not the bolt
threads in the ring gear.

Re: Dana 44 4.09 ring gear thickness
Hi Steve,
Yes, you've directed me the that site that indicates this NO NAME
manufacturer: Yukon makes the the thicker ring gears for the Dana 44,
before.
And the hearsay of these forums that their writers call themselves,
Rubi Noobie, and Rubi that tells me all I need to know about their
experience in performance parts.
But, hay don't let this stop you from buying a set.
