"Repacking front diff"
<font color="yellow">Sorry dude, but don't the rest of you guys find the image of a guy sprawled out underneath his Toyota, with a can of wheel bearing grease, stuffing gobs of it into the center-section of his differential... A little bit funny <IMG SRC="smilies/question.gif" border="0">
<IMG SRC="smilies/laughing.gif" border="0">

Seriously, if you haven't extended the vents on top of your axles with a new hose & fitting, drain & replace the gear oil in your axles every time you go through water deeper than them. The wheelbearings should probably be repacked about once a year, or about every 20-30,000 miles on a street-only truck, so use your judgement from there based on how hard you use the truck. I do mine about every 6 months, depending on how often I off-road it. It also depends on what kind of shape your seals are in - since newer seals keep mud & water out better.

The front locking hubs are a different matter from the wheel bearing. If your hubs are VERY hard to turn, they probably need relubed now. From my experience they tend to be most susceptible to water and mud, and need redone at LEAST every 6 months. More like 3 if you get into lots of mud.

Also, remember that unless you've done something about it, anytime you get water to the interior level of your truck, it also rushes into your transmission and transfer case...

The maintainence information I'm giving here is based on mud and river crossing type off-roading like we do down south, not rockcrawling.</font>

I have extended breathers ect just wondering how often you guys do it .We have lots of mud water ect. I was wondering about the knuckles I have new seals ect but after wheeling I notice grease on the round part of the knuckle and its dirty and slimy but I assume this is just normal.Seals are all in good shape so inside grease should be good I also use grease thats suppose to be work good in wet conditions.All in all just curious

in my last river crossing(unsccessful) i roasted the computer, filled the interior up to the middle of the dash...the front diff was full of water and i have breathers running to the area of the brake master cyclinder. also the tranny and transfer cases where full as well as the motor. did i mention the stinky mildew smell?? <IMG SRC="smilies/puke.gif" border="0"> <IMG SRC="smilies/frown.gif" border="0"> definitely repack the hubs too, mine where crusty and [email protected] up and i had totally rebuilt the axle with all seals, bearings just months prior...

hope this helps!

its not normal (well it is, not supposed to be!) the guy at toyota said as soon as the grease starts to build up on the outs of the seals ect.

there is also a way to pump grease into the birfield. just unscrew the "cork" and fill.
atleast that's what i think you can do. <IMG SRC="smilies/eek.gif" border="0"> <IMG SRC="smilies/question.gif" border="0">
