I noticed in the factory manual that the locknut does not appear to be the same as the 54mm. hex nut on the front hub. Is this another special kind of socket I need to get? Toyota shows a special SST, Haynes apparently uses a hammer and drift to turn the nut loose (!), but if one does that, how does one set proper pre-load when tightening it back up? I'm assuming I need this SST, anyone know where I can get one?

While it is difficult to explain, it is easy to do. Call me, or I can show you when we get together.

Compared to the front, the rear just SUCK !!. setting the pre-load when tightening up involves using a spring guage. no need for SST's - hammer and drift or screw driver is enough to do the job. but good luck. I found the front easy - and the mechanic said they were done fine. But, the back is hard to judge without the wisdom of at least a half-witted mechanic, and possibly one with all of his/her witts (are their any lady mechanics around?). The handbrake mechanism makes it hard to get a feel for hub movement i think. Anyway, the mechanic eventually fixed my rear ones up for me, after needing an angle grinder to remove the remains of the bearing from the stub axle ( long story, including axle seal failure and diff oil smoking things up ), whilst i hid my head in shame in his waiting area... From my DIY point of view, i will let the professional do the rears, while i am quite happy to do the front, incl birfields etc etc. Otherwise, get a good spring to measure the pre-load - I think my k-mart spring (from the fishing tackle box) might not be up to the job Scott Spackman - who is a better physio than a mechanic, and who has never caught a fish big enough to register on the scales anyway ;-)) HZJ80 etcetc To: 80scool@yahoogroups.com From: "r_callawa" Date: Tue, 15 Jun 2004 20:41:03 -0000 Subject: [80] '94 FZJ - Rear brakes rebuild questions Reply-To: 80scool@yahoogroups.com Fellas, Need to do the rear brakes on the FZJ: new rotors, pads and shoes for the parking brake system. To replace the brake shoes, do I need to pull the axle out to get behind the spindle? Most of the photos I see the Haynes manual show the axle out, but not sure if that is so we have a better view of if it is necessary. I have the new bearing and seals but don't know that I have time this weekend to do all that but I do want to at least get the brakes done as it sounds like the pad wear 'indicator' is starting to rub on one side. Oh, and if we do pull the axles it looks like this is the full floating system and there is no need to open the third member to get them out? Any special tools need for the lock nuts? Any other insight appreciated. Already did the birfields and front axle seals a while back, and figure this is a walk in the park in comparison.

Don't even need a hammer. PB is accessible after the rotor is off. To repack bearings, the axle is the first thing to come out. If you have an E-locker MAKE SURE YOU LOCK IT FIRST!

Do you have some gory story to share with us? :) the locking gear that slides over the axle is only held in place if it's locked. If it's unlocked, and you remove the axle, the gear can fall OUT! if this happens, you *might* be able to realign it with a broomstick if it didn't go too far, otherwise you need to pull the diff. I, and others have been lucky in that we didn't lock the locker and had no problems, but others HAVE had problems. It's easy enough to avoid said problem by locking the diff before disassembly. my 94 service manual doesn't mention it, but apparently others do. that is all...
