im about to change the front cv joint boot on my 4runner. I was doing some reading on it, and it got me wondering exactly what kinda of grease each one is. i didnt order the kit, i just bought the outter boot by itself.

reference i used.

The black or greyish looking Grease is a moly based grease. Very expensive stuff and must be used where it is said to be used or your new CV rebuild will go bye bye

 

You should buy the whole kit. If you're going to be rebuilding the outboard joint, then you have to take the inboard tulip joint apart also (to get the old outboard boot off and the new outboard boot on). Since you have to take the inboard joint apart, you will want to repack it with new grease, and you may as well install a new inboard boot as well since it's off and relatively cheap to replace. And use the specified greases (which will also come in your kit.)

 

Hi,

The yellow grease goes into the inner cv joint while the black grease goes into the outer cv joint.

HTH

 

gotcha, thanks guys, i think i am gonna return the boot i bought, and take the advice and get the whole kit and do both sides.

thanks guys.

 

The funny thing is, When I bought the kit from Toyota just the parts and the grease came in the box...no directions so then, how do you know where the grease goes? Where does it say to use it?

 

It is a rare occurence to get instructions when you buy parts. Typically, if you're using OEM parts, you can just put it back together the same way it came apart. (i.e. brown grease in the inboard joint and black grease in the outboard joint). If the axle that's in there now doesn't have the right grease (i.e. it's not from Toyota), then that's when discussion forums like this come in handy.

Good luck with the rebuild. Plan roughly 4 hours to remove, rebuild, and re-install your axle if it's your first time.

 

I just did the drivers side 5 weeks ago. time to do the pax side.

 

Very funny yo usay that.
I went to the Toyota parts dept. at Toyota of Knoxville today and bought a boot kit. Then I asked the guy which grease goes where...he didn't know...so he went back and asked the techs.....none of them knew for sure either. He tried plugging in the part numbers to see if one would pop up with inbd grease or otbd grease of something to that effect. One guy came out and said that in one of their classes that the instructor told them but he also was iffy wich grease went into wich boot.

Very strange that even Toyota doesn't know. Sad really.
