...vehicle problems that is. Noticed a couple days ago I was getting a sporadic yet brief vibration from the front of my '88 4rnr. I could feel it through the gas pedal, and I only really noticed it when in 5th at cty hwy speeds. It felt like a dry metal-on-metal rub, and it disappeared as soon as it came. I drive a few miles more, listening and waiting for it to happen again, and I got to thinking about my hubs. I've had them locked in for a few months now, but haven't used 4wd in a while. I pulled over, unlocked them, and drove away without another sound, shimmy or vibration at all. Seems like that was my issue, but I'm kinda stumped on remedying it. I can't seem to clear enough snow and ice out from around my wheel/hub/axle to find it, but I could have sworn there was a grease fitting to keep the hub nice and gooped up. I know when the hub is dismantled you lather it in grease, but isn't there a zerk or fitting of some sort? Am I losing my mind? I can't find my manual, either, so any help would be ridiculously appreciated. It's fun driving in 2wd rear an hour to work in the snow, but not always

Thanks all!

Do you have any lift?

naw, no grease fitting on there unless you drill, tap, and thread one in yourself

dont drive with your hubs locked unless your using 4wd

When the hubs are locked, there shouldn't be any movement between the hub and the axle end i.e. it should be like having a drive flange, ive never heard of a hub causing a shimmy. If you dont have ADD on your truck, your front driveshaft spins when your hubs are locked even when youre not in 4wd, so I would check that.

The freaking speedo noise is starting to drive me nuts again...I just haven't had time to take the dash apart and get to it...and I need to go get some chain lube.

Check your CV boots, you might have a torn one and losing grease. Keeping your hubs unlocked except in 4wd keeps them from wearing as much and is more efficient.

ADD truck are always driving around with their hubs (permanently) locked.

It only happens when it's cold.

Its fine. If everything is in proper working order, leaving your hubs locked will do nothing but wear out your componats from normal usage.

Perhaps some mud/ice caused an imbalance on the cv's or d-shaft..
And no, no grease fitting on the hubs, which only require a light coating of grease Way to many people pack these things full of grease and cause problems.

This thread remind me of the song by Corky and the Juice Pigs "I'm The Only Gay Eskimo". Something about the title.

This was a popular song when I was in high school. I'm procrastinating, don't want to study for a final in my least favorite course ever.

Jay351

Sounds like fun! what course?

I got class in the morning, I don't wanna go to bed yet

Ditto.........

I'd also check for play on the companion flanges for the CV axles......diffential side.

Ergonomics- the study of making workers/ consumers comfortable essentially. Boring as all hell. I've actually been reading up on Jeeps instead. That boring.
