4*4 ? 86 fj60

[Elbert]

Does anyone know what happens if you are missing the snap ring on the end of the axle (on one side)(front axle) 86 FJ60? Does...or can this casue the front hubs not to engage or the front tires not to pull when 4 wheel drive is engaged and the hubs are set to locked?

Went on a trail run near HiTop / Skyline, AL this date...Got off in the mud and then learned that the front tires were not under power. Front drive shaft is turning, hubs locked. Background.. .we installed new Auburn LSD in the front, new axles, new bearins everywhere, repacked the birfields, new brakes..etc.. RH front axle was missing the snap ring on outside when we took it apart, was not able to get a snap ring in time to replace by Sat an so we just went on without the snap ring on the passenger side axle.

I don't think the absensec of this snap ring would cause the front axle not to be powered, I"m leaning towards the (1) issue with the hubs, or (2) issue with the auburn LSD. By the way we intalled an auburn LSD in the rear and it seemed to work ok (same part number).

Symptoms are....front tires not under power when 4 wheel drive engaged, front drive shaft turns, 4 wheel drive light is on, hubs engaged.

If its the auburn LSD then I think the no-slip locker I took out of the rear may find a new home in the front.

I guess we'll take the hubs off to see what if anything...and jack it up on stands to see if 4wheel drive will engage on level ground. Anything ideas or stuff to look for?

Also question for anyone with a 60 +V-8 with marks adapter and yota 5 speed. Are you having issues with the slave cylinder "rod" over-extending and coming out of the slave cylinder housing at times (when this happens you are either locked gear or locked out of gear) depending on the timing of the event. Possible solutions? Thinking about trying to see if one of the adjustable slave cylinder rods from a 40 would solve this. There is no adustment on the OEM yota slave cylinder. Anyone seen this, and if so, do you know a solution?

Thanks, Elbert

I gonna bet its the hubs. You dont need to run the snap ring you can run a bolt with a big washer on the axle end too.


Early 60's have an adjustable slave rod. I know my 82 did before the swap.

Howdy! Sometimes when folks rebuild/reassemble the locking hubs, they put in way too much grease. It can prevent the hub gear from moving over to engage in the drive splines. Sometimes if you drive a round for a while after turning the lock knob, it will eventually move over and engage, but not always.

The snap ring is not mandatory, but it is a good thing to have, as it holds the axle/birf in the correct lateral position. John

I would start with that, that was done by the PO of my 60 and I found it on a pre trip check.

off topic...

but why did you pull a rar locker out to add a LSD? if anything i woulda run the locker out back and added LSD up front...

but then again im locked front and rear and love it. so my opinion may be biased.

got tired of the Locker working on the street. The richmond no-slip locker (power-trax) works very well. I just got tired of it on the street. In slow speed turns and parking etc....on pavement and concrete it tends to "ratchet", forcing you to continually be in coast mode with the clutch pedal depressed. Just my personal preference....what I'm trying to do now is get the front axle to work correctly.

As I recall the shop manual said "light coat of grease" for the hubs? I don't think we put to much grease in the hubs, but it might be the other way around and not enough. If the timing works out we plan to look at it again this coming friday.
