So working on the front brakes on my 66 and decided to check the wheel bearings .... and we all know how this story ends up.

Pulled my hubs off the drums because I'm going to replace my front drums. The grease in the hubs is bad so wondering can I pressure wash these things clean or clean in a parts tub with a brush then just replace bearings and pack everything or would that hurt something I dont know about?


I dont see a reason to replace them but I know I won't be sure until they are clean.

Thanks

Clean the bearings in solvent, pressure washing with water could cause rust. Then check their condition. If the bearing rollers aren't pitted, its OK to repack and reuse them. Check the bearing race in the hub too, if not showing pits or wear they are reusable. Never replace just a bearing, replace it and the race as a set. I'd suggest using new seals if you remove them or if they are years old. I prefer using the bearing packing cone type tool, I always feel reassured they are packed well when you see the grease extruded through them.

To be clean I'm talking about the metal parts the bearings go into. Same thing that has the wheel studs.

I'm replacing the bearing and races on both

I've seen some hubs completely filled with grease. Is that a practice taught somewhere? Its almost like they used boat trailer bearing buddies and pumped the hub full. I guess thats OK for boat trailers since most don't have brakes which would be contaminated by grease forced through the seal. I never put in more than the grease stuck to the freshly packed bearing.

Warhawk- Did you replace these bearings yourself the last time around?
I highly recommend not re-using taper roller bearings with an unknown history.
Only in theory do they LAST FOREVER. Who knows what your bearings have been
through. Replacement is cheap "insurance."
Don't take my word on it though, someone else on the VMF who also
works for a bearing manufacturer just might step forward. Or not.

Gt289. I was not the one that replaced the bearing last.

But I'm a little confused. The taper bearing is the outer bearing that gets filled with grease and goes inside the hub right?

I'm not reusing the bearings at all i plan on replacing both inner and outer once I clean the hubs. I'm only thinking of reusing the metal hub it self if there is no damage inside after I get it cleaned up.

Sorry if I was unclear on the first post.

Both outer and inner designs are taper roller bearings or TRB's in the industry. There consist of
two pieces, a bearing race and a cone w. rollers. They're typically packed with grease in the
Mustang world but could ride in an oil bath in other market segments and industries.

Are there any USA bearing manufacturers left? I think they are all made in China now. For that reason I'd stick with what was in there if they check out OK.

I've seen some hubs completely filled with grease.

I have seen that also and it is a complete waste of grease. The only grease that does anything of value is the grease that is packed into the bearing between the rollers. Apparently some people think that the bearings are pumps and they will circulate all of that wasted grease through the bearings!

What is the preferred grease for a disc brake type application? I have some Mobil 1 synth, the red stuff. Some Valvoline and another that I can't think of now. Also have some marine grade stuff for my trailer.

The grease pack thing is a hold over from the olden days. All you need is enough to lube them and not packed like a peanut butter jar. We were taught to pack the snot out of them way back in 197... err a long time ago. :pirate:

In terms of country of origin not too many bearings are made in the US these days at least not like it was way back when. Japan is still big (even though some of the Japanese companies use Chinese contractors), India and Germany are in the mix too. You can get good bearings from China. Look for brand names known for quality from a well regarded distributor/supplier and regardless of the COO you should find good product.

If you lube the brake discs how are the pads going to bite?...:stirpot::bricks:

I use the regular Lucas grease in the Mustang but for racing we would use either the Redline high temp (overkill for a street car) or the Lucas red sticky grease.

Wipe out all the excess grease and wash the remainder clean with solvent. Plain old mineral spirits works well.
Exactly how I do it.

Water from a pressure washer will blast the grease to smithereens, but it won't "clean" the parts. You need a solvent to do that. I use mineral spirits in my parts washer, followed by brake cleaner and blasting dry with air.


Here's the grease I use for hubs.

The Factory service manual for my '89 Toyota truck says to pack the inner hub with grease. It's a bit vague as to how much though ? IIRC it's to help keep the oil from separating out of the carrier and migrating into the inner hub area, making a physical damn of sorts ? After all, grease is just a suspension of oil in a carrier or thickener ( like clay and lithium IIRC ), which can separate over time and with temperature.

All tapered roller bearings I've seen are basically the same. There's no reason to jam-pack grease into the hub. When I've cleaned a hub and used grease correctly I find it pretty much stays put. There are cone-shaped tools to quickly repack bearings off the car with a grease gun. I suspect some shops may slap repacked bearings into a hub already full of old grease.
