Looking for a Seal

[lostforawhile]

I had to cut that big stupid metal labyrinth ring off of mine when I did the teg shafts. Turns out the accord cv ends have a ring machined into them to accept that, whereas the teg cv's don't. Once I was done, it resembled an ordinary oil seal, which i pressed into the hub. I imagine that you could get an oil seal that matches the ID/OD as required, remember that the seal needs a few thou press in order to retain itself in the knuckle.

i'm working on that now, I just picked up a masterpro set of seals for the disc brake/hubs on my Lincoln and they look just like the seals on the 3g, I'm going to try to contact them to see if they have a breakdown of seals by size

I was able to remove those knuckle rings on my old hubs with no problem at all, and put them back in. just some light pressure from a screwdriver in different places, so they are reusable. I went out a little while ago and tested it

That was my experience as well. They are so easy to remove I'm surprise they stay in place as well as they do.

So, I got my package from Rock Auto today. The bearing they sent me is an NSK that says "Japan" on it. What I ordered was a Timken bearing. Since they do not even list NSK bearings on Rock Auto I am wondering if this is a comparable, high-quality brand. Parts Geek is going to let me return the Koyo bearing.

NSK is an excellent bearing, I believe Honda used that bearing new. I know my originals are NSK

Thanks, Lost. I couldn't really tell much by looking at it. I'm keeping my fingers crossed that once it's pressed in it won't have play in it.

I would have no problem putting an NSK bearing in my car, just make sure it's a REAL nsk bearing, there is a major issue going on with counterfeit Chinese made ones. You said it came from Rock Auto? might want to check with him to make sure it's real

This is what I got for mine when I did mine about a year ago or so http://cgi.ebay.com/ebaymotors/2-WHE...ht_1477wt_1165 Precision Automotive is what brand they are and they are nice and quite. Of course I have my own press and stuff too so I know there were no installation errors. Good luck hope you get it sorted out okay.

[DBMaster]

Uh, yeah, I'm sure that a C/S rep from Rock Auto is going to know whether or not the NSK bearing, which they are not even "supposed" to carry, is real or fake. Not to be flippant, but I doubt that is going to be the case. I looked at quite a few bearings online and bearing/hub kits. My hub seems fine, straight, and not rusty. I have used oil on the lug threads since the car was new to prevent rust and lockup. I read that you're not supposed to do that, but I have had good luck with that procedure for 30 years. I just want this issue resolved since it should be fairly simple. I am not comfortable using a hammer for installation like Snooz did.

I used to feel that way too. Then I took some control arms down to Pep Boys to have new bushings pressed in. When I got the arms back, they were so beat up that I demanded they replace them. The tech obviously didn't have the right arbors, so he just kept trying and bashing the ram into the arm when it slipped off. He pushed the rubber out of the bushing. It was a real mess. I thought, I paid for them to do a worse job than I could have done with a hammer. I've never looked back since then. It's really easy. If you were nearby, I'd drive out and help you. Don't do anything you aren't comfortable doing though.

you need to press them, if you hammer in a bearing you are going to damage it, you are hitting the bearing rollers and cage together, thats the same reason you never hammer on a cv axle, unless you are junking it. they are precision bearings, do it right

[Dr_Snooz]

I couldn't possibly put more force on it with a 4# sledge than is going on it when I hit a pothole at 70 mph. There's just no way.

it's the angle, when you hammer it in, you put a lot of side load on the bearings, that damages the bearings and cage, the load when you hit the pothole is completely different. the weakest point of a bearing assembly is the side. The bearing installed into the hub is also a lot stronger then when it's by itself. when you press a bearing in, you have an arbor which is putting constant load on the bearing, vs. the sudden load from a hammer. when you hit a pothole, you are loading the bearing and race through the axis that is strongest,vs the side of the cage which is weakest

Okie dokie. I'll let you guys battle it out on this one. I took the NSK bearing into my shop and this time there was no play. Once the old bearing was out I checked it out as I am sending it back for a refund (warning: Parts Geek does not refund outbound shipping, nor do they issue a shipping label for a return). I may get the $35 back for the bearing, but I'll be out about $16 in shipping costs.

The Koyo bearing had no noticeable play when it was pressed out. It looked undamaged. I found out that the grinding noise I heard for the first day was the axle rubbing on the inside of that metal "ring" that started this thread. It was nice and shiny and quite reamed out. It's like the other bearing wasn't even quite right because it positioned the hub slightly too far outward resulting in rubbing when the axle nut was torqued.

Long story short, it's fine now. Thank you for all your suggestions.

You guys are both being stupid. You never apply force through the bearing. If it's going into a bore, press on the outside race only. If it's being pressed onto a shaft, press on the inside race only. End of story.

There are rare exceptions where you may transmit force through a bearing while it's rotating, which avoids brinelling the races with the rolling elements. Although you can usually avoid this with liquid nitrogen or an induction bearing heater.

This is why I never trust taking a vehicle to a shop. I just replaced the AC condenser in my wifes car after the dealership stabbed it with the rad support, while they were changing the rad fan motor on warranty. Of course the warranty ran out before we discovered the AC was dead, as the fan was changed in the fall when the AC wasn't being used. Think the dealership would fix it? They denied all responsibility, even though the damage was behind the rad support crossmember right where the corner of it comes close when pulling it out. Like the tech didn't notice when half a kilogram of refrigerant pissed out in his face. They also left out all of the hard to get to bolts.

[Dr_Snooz]

^^^ Right. You hammer on the race, not the ball bearings. That would be crazy. I mean, give an idiot a hammer and he can destroy just about anything, but the same holds true for hydraulic presses, as I found out. If you know what you're doing and you're careful, it's a great way to do your own bearings.

[lostforawhile]

I should have clarified, when i said the race, I'm used to working with two piece Timken bearings, which have the rollers and cage as one part, and the race as another, I also deal with one piece roller flange bearings every day, which need to be pressed in. The worst thing you can do to a bearing is hit it with impact forces from the side, I know not to put pressure on the rollers. I've been working with these bearings nearly every work day for almost 12 years, I'm not trying to start an argument, I'm really not, I just don't want someone to spend a lot of money on bearings and have them fail down the road because of an installation mistake

[DBMaster]

I innocently asked the shop if they supported the inner race when pressing in the hub. They said, "Of course." Like I said, after seeing the Koyo bearing it appeared intact and undamaged. There was no play that I could feel, but once it's in the knuckle it's there. I'm just glad it's done. I can think of a number of hard knocks that right front bearing has taken over the years including two curb impacts that damaged wheels. It's no small wonder that bearing wore out first.
