Landcruiser Broken Wheel Studs

Yep, the 6 stud Landcruisers were notorious, but with the 5 stud it is a rarety.

Mick's were 5 stud - the studs are bigger (14mm instaed of 12mm) so are stronger and have a higher clamping pressure when correctly torqued.

One thing I've noticed is that the factory Toyota wheels are a firm fit where the centre hole slides onto the hub, so there's very little movement when nuts are loose. The aftermarket wheels have a centre hole thats about 2mm bigger and if nuts work loose, theres some play between wheel and hub.

I have broken one on 7 yrs on my 100 ser with factory alloys and I went down to Don Kyatts and bout some spare stud and nuts which I leave in the tool kit of the 4B

Cheers john.

Having owned various FJ 40's, FJ 55's, HJ and FJ 45's, FJ 73 and HZJ75 all with 6 stud pattern and heaps of overloaded trips such as CSR, GRR a few of Mr Beadell's "highways" and never having broken a wheel stud my advice is when you need new tyres remove your wheels at home, take them to the tyre joint of your choice for fitting and balancing, then re-fit at home without a rattle gun. If you know how to tighten by "feel" fine, if you don't, use a torque wrench.
Then re-torque after a short run.

Phil,

Must be a rarity as I have done two studs on one front wheel and one in the rear. All replaced under warranty. Now carry a few spares. ;)

Well there ya go........
I guess that makes it almost a rarety :-))

Not proposing that it doesn't happen, just what I have done and the end result.
IMVHO the other possible contributing factor is much larger tyres and rims than standard.
