Thread: Axle bolts loosening

Is this the same hub that had the broken bolts, Ryan?

Wasn't there a problem with removing the broken bits because the bolts were Loctited in?

Had the same issue on mine recently after re-using an old gasket.
Pull the drive flange off, clean out the holes to make sure there isn't any old sealant etc in them, then refit with silicon on the flange and a tiny bit on the threads.

Shouldn't need to loctite them IMO.

Yes, Loctite is the answer.

Make sure the threaded hole and bolt threads are extremely clean, oil free and dry before re-installing.

Also check that there's no wheel bearing play (and nip it up if there is) as that can cause this to occur IMO.

[edit] Drive flange bolts are 65Nm-48lb/ft

If you are talking about the drive flange bolts, then definitely loctite them. They have a bad habit of working loose, or snapping inside of the hub. I believe that this is exasperated by loose bearing adjustment, exuberated driving or larger tyres.

Yes, in my experience loosening drive flange bolts are almost always a symptom of excessive bearing free play.

Ranga, Does your vehicle have Maxidrive driveflanges? Regardless,if the bolts still loosen or break after following the above suggestions, suspect a bent axle housing or stub axle.It would also be interesting to spin the halfshafts between centres and check runout at the splines.Shafts tend to bend with heat treatment, and if straightening isn't done meticulously the inner and outer splines may not be exactly parralell which can lead to premature wear and/ or extra strain on the flange bolts.
I did however cure a persistant bolt loosening problem on a friends series 3 by replacing the bolts with studs and nuts.

Funny you should mention that Bill.

One of my old Jeeps had a D60 rear end with studs and nuts and IIRC it had little tapered collets as washers under the nuts in the drive flange. (I think. It was twenty years ago )

Toyotas have the same setup, PIA to remove the cones, sometimes, Regards Frank.
