I read use moly fortified grease while doing the birf.
My wife just came home with four tubs of MOBIL 1 Synthetic grease, can I use it or do I need to return it.
Thanks for the help with my newbee questions
It's ganna be my first time :eek:

I've used Moly fortified, standard wheel bearing and chassis, and Valvoline red junk (a little better than the standard wheel bearing stuff).

Some dudes here are pretty picky about grease and oil etc. Its grease, its new clean and lubricates. Sounds good to me.

Yes the mobil 1 stuff is fine. Pretty damn pricey though.

Its not a big deal, just take it slow.
 
Steven, a quick SEARCH will elucidate the many posts about the evil of not using moly fortified grease.

I personally agree with CruisinGA that it won't mean doodley squat. But I like to tear apart the front end every other month to make sure it's all still there...

So my advice would be to call around to the local auto parts places that you're actually likely to go to on short notice and check on their availability for the moly-fortified stuff. If they don't have it then use what you have. Mine is currently crammed full of the red Mobil 1 syn and I have no issues.

Good luck on the rebuild.
 
I use two different grease when performing maintenance on birfields. I use Amsoil Synthetic Multi Purpose grease lithium base for wheel bearings and Amsoil heavy duty moly-fortified grease for the birfields and inside the knucles. The Multipurpose is red and heavy duty is dark purple.

I'm with him, grease is grease is grease. Make sure it is clean and in there.

Which brings me to another questions altogether - is it really a big deal to "mix" different types of grease? I have heard that this should NEVER be done......why?

The grease I put in the Birfs was from a can. If I top off the fill plug (on top of the knuckle), it will be from a tube (a grease gun) and will most likely not be the same.

Why would this be bad?
 
If grease were grease (all the time) then Mr Toyota and others wouldn't spec more than one kind. In this case, after some time in the birfs, some grease is not grease.

As I understand it, the moly grease leaves some lubrication in place even when the grease is dissipated, dried out or displaced. It is specified in situations where there are long intervals between service, which might even be extended by neglect!! :D

I would suppose bearing grease is fine too, as long is it is redone more often than the moly. I don't have any idea how much more often

I agree with TLCgrappler....Toyota had a reason for spec'ing moly and it wasn't to sell more moly grease. Moly grease has the best properties for adhereing to metal surfaces, which is important in the birfield. Moly also has better load and pressure-bearing properties that other greases. The moly content makes it a better grease for something like a birf.

While I'm not picky about my lubricants and oils, I would still never mix grease.

I've got two cheapo grease guns, one for standard, one with moly.

Honestly, you shouldn't ever need to add grease through the fill plug. The only possible benefit is displacing any other fluid (water, oil etc). And by that point you already need to tear in there.
 
I used Amsoil moly in my birfs, and Mobil 1 synth in the wheel bearings, but the M1 is not moly fortified. If you're doing wheel bearings, you'll need about a tube per axle - just take a razor knife and split the tube like a freakin' sausage for wheel bearing packing.

Thanks everyone.
You told me what I was woried abour Doug.
M1 is not moly fortified
And Toyota does ask for moly in the birf.
A drive into town is a good excuse to get a coffee :D
