Preventative Maintenance Neglected, D30

Rust, Dust and a Lunch Box. [img]/ubbthreads/images/graemlins/smirk.gif[/img]

OK, I was real quick to point out Jim Lou's neglect of his sad old AMC20. Here are a couple of pictures (just teasers) of my sad little Dana 30 front as I took it apart.

The difference is time, not even a year here.

Santa was very kind to drop off a Locker for the front of my Junk.

Rust





When the wheel bearing grease turns to red the friction is reduced isn't it? But why does it feel like 80 grit?

Dust



Where's the problem... the bearing is still there... well some of it. Should I use a vacuum cleaner?



Well there's why I tore it down... Do you think maybe, just maybe I should have, would have, could have cleaned that darn thing up and tossed out some mud/in some new grease??

Naw.

Re: Preventative Maintenance Neglected, D30

Might have been a good idea.

I should do my fronts - haven't had them apart since the bash. It's almost time for the bash again, isn't it? [img]/ubbthreads/images/graemlins/grin.gif[/img]

Re: Preventative Maintenance Neglected, D30

That's why i like unit bearings, buy 1 lifetime set of them and no worries, just replace them every couple years. I'm going to hate greasing my wheel bearings every couple runs.

Re: Preventative Maintenance Neglected, D30

The problem with unit bearings is the cost when you have to replace them. Ask Rio.

Re: Preventative Maintenance Neglected, D30

Yeah, like rio said they are about $100 a side for life times. If you compare that to a set of good lock outs, new wheel bearings, a new spindle and hub assembly when you forget to grease your wheel bearings and the regualr maintaince to grease them the $200 for life time unit bearings that are a 1 beer job to change doesn't seem so bad.

Re: Preventative Maintenance Neglected, D30

Ya know... it's the time that's taking it's toll.

New wheel bearings, the hub bearings & wear parts all come to a bit less than $100.

I have spent hours and hours cleaning out mud/rust/crud. Just getting those silly needle bearings out of the hubs was some fun, and likely a 45 minute job. A bit over an hour scraping out and plunging through the axle tubes alone. Near endless scraping and wire brush time.

Still haven't put it back together... But as of tonight all of the parts are cleaned up, repacked with grease and ready to reassemble. The floor under the darn thing is even clean, there's always tomorrow.

As for unit bearings... I will always hate them because of my work truck (Blazer).

Re: Preventative Maintenance Neglected, D30

You mean they don't come new with hunks of rust, mud, and broken bearing parts? I figured they must, since they all have it.

Wonder if it might be a good idea to toss in a handful once it's clean?

Re: Preventative Maintenance Neglected, D30

A complete bearing as a single unit - race, cone, rollers, cage and seals - lubricated "for life" at the factory.

As opposed to bearings with separate components that you disassemble and regrease periodically.
