Xtreme Toyota Part
out the Toyota rear axle for a Chevy 10bolt
Date Started: July 2003
all started when I noticed some fluid leakage
coming from my rear passenger side axle housing.
Take a look : (
figured that one of the bearing seals had just
given up and I anticipated a quick and painless
operation. I was actually looking forward to
swapping out the bearings and seals since I
had been expecting them to give out at one point
or another. Then after a weekend playing around
in the dunes
of Pismo I was expecting to hear
some noise from sand binding up in the rear
drum brake housing, but I heard none. Upon closer
inspection I discovered that the fluid wasn't
coming from the outer axle seal but from
a crack surrounding the spring perch.
I did some investigating on the subject and
I've been hearing more of the same problem happening
to other Tacoma owners. I've heard of the axle
housing being priced at $1000 and figured that
with bearing and seals that the total cost would
be way too much for a rear end that had the
wrong gearing for 31"+
tires, an open diff and that
would be prone to cracking in the future.
not planning on slowing down and I plan on finding
some more quality off-roading in the future
so I've decided to do a proper job and do it
right. I've contemplated re-inforcing a toyota
rear end but the cost of just the parts alone
had me disgusted. I have quite a bit of experience
with the Ford 9" from an older drag F100
I used to cruise and what a great piece of machinery
that was. Anything that can smoke fat tires
all the way onto the freeway from the intersection
and smile is A ok in my book. My Toyota can't
quite smoke'em but I do want a bulletproof setup.
Modding a 9" rear end starts getting expensive
because it needs to be narrowed carefully. What
next? Well a friend of mine suggested
a Chevy 10 bolt out of the rear of an S-10 pickup.
Have you ever heard of a rear axle like that
failing? Not me. I found one in the bushes and
started going to work.
man's trash is another man's treasure!!
here is the interesting part. It just so happens
that this rear end is outfitted with a positraction
diff AND 4.10 gears...jackpot! Now
all I need to do is get my 6 lug rims to mate
to the 5-lug axles. It is possible to have them
drilled out to fit BUT who wants to use drum
brakes? I have resources enough to order up
some custom calipers and have even found some
adapters. But what about the master cylinder?
No problem. It just so happens that the Toyota
Landcruiser (FJ80) comes outfitted
with four wheel disc brakes so naturally that
is the answer. Do NOT use the stock master cylinder
with rear disc brakes. Disc brakes require more
pressure and also something called a residual
valve. The FJ80 master cylinder is the answer.
So after I get some custom axles machined up
and my brake parts in it will just take some
tinkering and adapters and I'll be in business.
are a lot of specifics I've left out for the
sake of boring you all and I don't want to post
anything that might lead someone to putting
together something that doesn't work perfectly.
I am confident that what I am cooking up will
work but please don't hold me to the information
I have shared with you thus far. I'll let you
in on it all once I have it all the loose ends
tied up!! Here
are some pictures of the progress made thus
