Exclamation Hub Bolts

Was walking by my truck yesterday when I looked down at the rear wheel. One of the hub bolts looked loose and there was a bit of 90wt on the wheel. After a quick inspection I found ALL the bolts on all but one wheel I was able to back out by hand. Both rear wheels and the right fron wheel hub bolts were all loose. I have had not worked on or had any work done to hubs since I have owned it for over a year. Now I have a new weekly check . Anyone experience this before?

Sounds like someone forgot to use threadlock. I saw it happen to a disco before, took the bolts out and turns out 3 were broken off half the way down the threads, Make sure you back them out and check them.

Make sure the stainless are the proper grade. There is a lot of stress there.

I am assuming they are grade 5 or better. I will take a look.

Thanks

Those are at least grade 8 bolts in your hubs. Grade 5 *or* stainless (which is not much stronger than grade 5 - it's in the same ballpark) should *not* be used for any high-stress applications. Do *not* use stainless for your hub bolts!!!!!!!!!!

You deff want the bolts that steve list. Also there are a lot of different opinions on this, but i use a new paper drive flange gasket. Some folks just run a bead of "the right stuff" around drive member-but this distorts proper torque setting. And lastly torque all bolts to 48ft/lbs aprox. 64nm. I thought 48ft/lbs was a little low, so I adjusted the torque wrench to 50 and broke the first bolt. So 48is important and will help reduce loose bolts. Also use a med locktite on threads. Rock on JP
PS Dont settle for Grade 8 bolts, You can find correct bolts at most auto parts stores or any LR parts warehouse.

JP,
Thanks, I have a good source for nuts and bolts here in Burbank, Lukys Harware. They are a aircraft surplus hardware store and have every grade nut and bolt under the sun at great prices. Thanks also for the torque settings.
