75 series ute

[878ROB]

Hey everyone, I am new to this website, My name is rob and i have just recently purchased my very first fourby, 1991 75 series landcruiser 4.2D...

I just have a few questions, Today i was driving about 20km/h down a side street and i went to pull in a driveway and turn around, I reversed out the driveway and put her into 1st and took off like a grandma, slowly reached 2nd and as i released the clutch to engage i heard a loud bang and then i had no forward movement. I jumped under the back and i noticed my tailshaft spins very freely, while spinning it i can hear a clunky noice behind the dust cover on the LHR wheel hub. Not only a noise but the dust cover is covered in inverted dents from something being belted around inside...

Can anyone help me out and maybe tell me what may have gone wrong and what i need to fix it.. I work in a wrecking yard so parts are very accessable for me, Any help will be greatly appreciated.

Regards Rob

You've snapped your axle drive studs, the inner axle is now loose in there being held in only by the hub cover. The studs probably broke due to poor or incorrect assembly/maintainence, possibly worn bearings (assuming you have an open differential). Or previous abuse.

You'll need top replace the entire hub or drill/ezy out the old studs and replace. You may also need to replace the bearings if they were indeed what caused the damage to the studs. Use new cone washers and assemble with correct torque, re-torqe after a few hundred km.

If the inner axle is bent, twisted or has a damaged flange this will need to be replaced too.

Couldnt comment on labor costs sorry. Easy enough job for a home mechanic with some experience, a brass drift, a torque wrench and a spring scale. Replacment hub/washers/axleshaft/bearings would come to around $300 i'd imagine...

That's the way A full floating hub is something you'll never have seen the likes of before

Try and get your hands on a genuine toyota workshop manual - probably an ebay job and may take some searching but most definetly worth it. I've had 'aftermarket' manuals and they're useless; probably good enough for service work though (i.e. wheel bearings).

Had the same problems when I bought mine 12 months ago.

Bought a new axle (to be on the safe side) and a good hub from the wreckers. Put back together with new seals and check the studs weekly. Has been fine since.

I have a 100 series conversion kit if you are interested.
its larger 10mm studs, cone washers etc.

Machine a drillbit to the correct taper and drill outer flange / axle in a drill press - and you have 10mm studs. You will need to punch a large hole in the drillpress though to let the axle through.

Thanks mate but i think ill just keep my original diff until i play with the bigger toys.

ok so i have finally pulled the axle out and sadly shes shagged, the flange looks like it has been belted with a hammer previously, looks like im also up for a new hub, i think the bolts have ruined the thread inside, but i will buy all parts to fix it anyway, wheres the best place to buy the bearings and seals and bolt kits?

[878ROB]

oh not to mention the bloody thing is bent too, but it wouldnt suprise me if it was bent before i got it.

Welcome to the club!

If your thinking of buying from the wreckers, check new prices first. I've been quoted more for used parts than new a few times now.

Hey Rob,

Worth cheking prices with Sunshine State 4WD before you shell out any cash for your spares. They are in Kerry Road Archerfield. If you get stuck, sing out, there are lots of people here that will help you.

Cheers

[878ROB]

Hey guys, i finally got the ute fixed, did it myself, cost me $65 for the axle and $110 for the hub second hand, $2 for the axle flange gasket lol and the use of my mates jack and i was set, didnt take long really, had some helpfull tips n tricks from my local 4x4 centre..... BUT.....however i still have a problem with it, as far as im aware that the axle slot is worn on the outside where the bearing is seated, thats what caused the 1st problem, so i think i may be up for a complete diff soon or a thorough rebuild..... cheers for the useful info guys much appreciated..
