Busted Pinion

[Captain]

I busted my rear pinion this weekend and need to start locating a third
member so I can hopefully make a run in two weeks. Lots of folks told me
where I could get one while we were on the trail but I didn't take notes
and CRS.

I've got a '72 with 4:11's. My drive shaft is also cork screwed so I'll
have to change it also. Someone said it would be a good time and idea
to upgrade to a fine splined pinion. Again I can't remember what years
he said they are available.

Any help would be appreciated!

Thanks,

fine spline 4.11 gearsets are available in 1978 FJ40's if you are lucky, otherwise in 60-series wagons.

Been there, done that, carry a complete prepped spare diff at all times (on the trailer) and a spare pinion in the tool box. My current coarse ring-pinion has been cryotreated and hasn't busted. (Not sure that's a cheaper cure/end all cure, but so far so good....)

All aftermarket R&P's are fine spline...

I'm looking for a complete third member. I trashed it all!

maybe post in the wanted corner?

and to correct woody.. FJ62's had the fine spline 4.11 gears not the FJ60's.. But Fj60's were fine spline just 3.73 ratio.. Way cheaper to get a spare course spline third, most of us keep our spare 4.11 fine spline chunks. Might be a cheaper solution to just re-tube your existing axle parts. Stock cruiser driveshaft is 2.563" OD with .056 wall. Dana/spicer tube available at the machine shop or Napa measures 2.75 OD with .083" wall. thus sleeve your old plugs and make a new shaft.

knew I'd get that backwards..... unfortunately, it limits you even more. ...and Erik is right most folks hang onto 4.11 fines...I was VERY lucky and found someone who just upgraded the gearing in their wagon, now have two sets on the shelf for future use.

Email CRUSRDAN@AOL.COM. He is in Tulsa and may have a fine spline 4.11 rear axle at his house.

I've got a course spline third out of a '66...not sure if it will work in your '72 though. You're welcome to it if it'll work for ya.

I've got a cource spline third out of a '66...not sure if it will work in your '72 though. You're welcome to it if it'll work for ya.

if it has the larger mounting stud holes, it will work
