Loose Hub Nuts - GM 10 bolt

[JCampbell]

'88 K20 Suburban

Back in September, I noticed that my driver's side wheel had a shimmy in it. Traced it back to a loose hub nut. Tightened the nut (torqued till wheel wouldn't spin, backed off a touch, then sucked up the "lock nut"), and buttoned it all up. The passenger side was the slightest bit loose, so I did the same thing on that side.

Jacked the truck up to R&R the brakes, and I noticed the driver's side is loose again. Passenger side is still tight. Something doesn't seem right.

Any thoughts?

Wheel bearings taking a hike. Time to take them apart, clean them up and see what you have. If anything maybe a repack is in order.

Replace the bearings, tighten the nut, make sure you use the washer after the nut (has the little pin in it), then tighten the lock nut as tight as you can crank on that sucker without the socket slipping off (ouch).

Okay...I see what you're talking about regarding the washer in between the two hub nuts. I see that there are a series of holes drilled along the diameter of the washer that I'm assuming would take some sort of pin to keep the hub nut from backing off...but mine has no pin(s) in it. The same was true when I took it all apart back in September.

Is the retainer pin(s) something I can source at Napa?

The pin is a part of the inner nut. You'll need a new nut--they're about $10 each. Napa generally stocks them.

Here's a link to one place that sells them if you can't find one locally:

When I needed one, Napa was out but a local 4x4 shop had them.
