Toyota Birf replacement 101

[Canadian_zuk]

I know alot of people on this board are running Toy axles under their Zooks, and most know all about birfield replacement. I had to do one yesterday, so I figured I'd detail it and make a post for the newer guys that haven't gotten that far yet.

Here it goes.

(1) jack up front axle on blown side
(2) remove tire
(3) remove Caliper bolts
(4) remove caliper
(5) place caliper out of the way

(6) remove 6 10mm bolts in locking hub cover
(7) remove locking hub cover
(8) remove 6 12mm nuts & lock washers retaining locking hub body
(9) remove snap ring from stub shaft
(10) tap around locking hub body with hammer to loosen it (brass hammer is safer)

[Canadian_zuk]

(11) remove locking hub body
(12) clean grease from hollow & bend lock tabs away from the jam nut
(13) remove jam nut, locking tab, & retaining nut from spindle
(14) remove wheel hub & rotor assemble from spindle (careful not to drop wheel bearing)
(15) remove 8 14mm spindle bolts

[Canadian_zuk]

(16) remove the spindle
(17) remove all shrapnel from inside knuckle (clean it good)
(18) replace axle seal if damaged (I use a large socket with an extension)
(19) install well greased replacement birf & axle
(20) ensure flat spots on birf are at 12 o'clock and 6 o'clock to clear kingpins

what size tires are you running on that yota and was that a stock brif?????

and will we be getting the pinion seal 101 next :thefinger

[Canadian_zuk]

(21) clean up & apply a bead of silicone to back of spindle
(22) install spindle over well greased stub shaft
(23) ensure all 8 bolt holes line up & spindle is seated on knuckle (will only go on one way), torque all 8 14mm bolts to spec.
(24) reinstall rotar & wheel hub assembly, first spindle nut, set bearing preload, install lock washer and jamb nut. Bend locking tabs over nut flats.
(25) clean up & apply silicone to hub body, install over stub shaft.

(26) install clip, locking hub cover & brake caliper.

You can probably figure out how to get the tire back on. :thefinger

33's, yes stock birf.



and will we be getting the pinion seal 101 next :thefinger

Pinion seal?? How do you know if there's gear oil inside if it isn't leaking out? :huh: :thefinger

Hummm, I didn't I watch you do this first hand on the trial, behind the coke plant sunday morning, ABIUT 3AM?
That was a fun run, so let's get back in there agian soon.
Bring all the Dad's too, OK!

That was very thorough CZ, just like the manual describes. :) However, I never pull the hub off on the trail (or in the garage for that matter). My prefered method is to simply remove the whole knuckle from the back after the caliper comes off. You only need to remove the upper kingpin/steering arm and the ten bolts holding the backing plate/rubber wiper/felt from the back of the knuckle. It takes all of maybe 30 minutes from begining to end to change out a birfield in this fashion. Plus because the whole knuckle comes off you can clean out the trunion bearings as these usualy have some fragments of old birfield cage inside that need to be cleaned out.

I wish I had the time to document that procedure in the excellent fashion you just did here but I don`t. Instead, I posted a well documented procedure for something else. You can find it here (http://www.zookpower.ca/forums/showthread.php?p=27992#post27992).

Just to bust ur balls a tad.... The knuckle method u descirbe is also my fav for on the trail.. its fast and much easier and cleaner but 2 tings worthy of mention...


1 - u STILL have to remove the locking hub cap and c-clip off
2 - those 4 cone washers on ur kind pin bolts dont come off to easy if u havnt had it apart in a while.

In the shop, I prefer wheel bearing method as described.. gives u a chance to repack and retorque all those critical parts. On the trail.. Kind pin all the way but sometimes that takes another set of hands to get the splines to line up.

nice write up.
but man that sucks you busted one with just 33s. i thought you where pretty safe with 33s and a stock birf?

Hehe, oops. Forgot about that. I bought the special pliers for those c-clips (Princess Auto special) and since then I don`t have to fight with them.

As for the kingpin cone washers, anybody running a Toy axle would do well to remove the kingpins at least once and clean things up a bit before ever wheeling hard. I had to fight with those puppies in the shop with the big tools never mind trying to get them out on the trail! When I rebuilt my axle I used All-Pro`s knuckle rebuild kit and it came with new kingpin studs and cone washers. I have them apart at least once a year so they come off pretty easily.

If you Martack your axles, you don't need to run the hub clip or the inner birf clip, which makes the knuckle method even faster. But alas, I've never removed any of my kingpins, that's why I chose the hub method. Last year I went through 6 or 7 Sami Birfs, I got to the point where I could swap one out in under 20 min, that's scary. :beatup:

Was that blindfolded and with one arm tied behind your back or just blindfolded?
:beatup: LOL.

That was on Wednesday with 86Sami. On Saturday with Extremekickin, ZookVet & Fullload I had bigger problems. We were playin in beheind the Coke plant and this stupid little hill (more like a wall) wouldn't let me up. Not one who likes being denied, I gave er, Depot style. The guys that were there said I was catching 3+ feet of air while trying in reverse. On my third run at, in my third round of attempts, my uncle informed me my passenger tire was no longer turning. I peeked out the window to see it cranked fully to the right, normally this wouldn't be of much concern, but unfortunately, my steering wheel was cranked fully to the left. :beatup:

The tierod was complete missing from the front axle :rofl: & another broken Birf :roll: . Luckily Fullload had a spare tie rod 20min away, while him and a friend were off retreiving the spare, I removed the broken tie rod ends and fed the mosquitoes. I looked for the missing parts for 20 min :huh: , never did find em. Got off the trail with the replacement tie rod, and pulled the broken birf on the road. Finally got to head home around 4:00am.

Sean :D

no, usually just knee deep in mud, being chewed on by bugs. It's amazing how fast you work without DEET! :D :D
