MOOG 512396/7 rear wheel bearings

[Malleus]

Anybody have any experience with these as replacements for the OEM cartridges?

MOOG-512396 - Rear Left Wheel Bearing Module made by MOOG

I've been trailering a 16' tandem axle utility trailer, sometimes loaded to the maximum advertised weight, infrequently, for about a year now (without trailer brakes, yes I know, I shouldn't, but I did). Just put new Michelin LTX M/S2s on all four corners and now there's a bearing noise that wasn't there before (I assume the old tires were masking it). So now it's time (@ 100k) to replace the bearings, any thoughts?

If it is a bearing, I think you would be the first person on Mud to have a failure in a 200. Definitely keep us posted.

I'm going to pull a rear wheel this weekend and take a look. The Federal-Mogul bearing specs suggest replacing the axle nut when with the bearing. Any thoughts? I don't have a FSM, so if anyone does, could I borrow a peek?

There is a link to the FSM in the FAQs section.

Thanks, I'll give it a look.

Did you move forward with the wheel bearing replacement @Malleus? I have a new to me (very) high mile LX and think I need to do bearings too. Any pointers?

 

[Malleus]

Well here it is, a little more than a year and 30k miles later, and I decide to turn up the stereo. The doom and gloom predicted by the dealership which diagnosed the "bearing in danger of imminent failure" is still waiting for my money.

What is "high mileage" and what are your symptoms?

This is, IMHO, a job, as you have to fully remove the axle, cut (using a die grinder) the cup (bearing race) from the journal and press (using a hydraulic press) the new bearing on. It's a straightforward job and anyone who's done this on a Ford or GM 9" or 10" rear end will know exactly what to do. The caveats are you HAVE to have the equipment. Renting it is only half the solution; this job takes up a fair amount of room too.

FWIW, I'd rate a differential build as (because I've done a few; most would add one) and the transmission rebuild as .

209K miles. There is a bit too much noise in the driveline, from 20 mph up. It has famously noisy Michelin Latitudes on it, but there is a bit more noise and vibration than I want. I suspect wheel bearings because the noise is velocity dependent, but not gear dependent. It could be a bit in the wheels and a bit in the diffs, I am inclined to suspect the bearings.

I would just blame the tires, but from what I've read on these, while noisy, they don't have the characteristics otherwise I feel (vibration), and the tenor isn't quite right for tires . . .hard to explain but i know you know what I mean.

Sadly I have no press or die grinder, so I'd have to pull the axles and run them down to a machine shop too.

I also want to do all four corners . . .

 

[grinchy]

I need to pull the wheels and see if there is any play when I twist the rotors.

Take a breath. My "diagnosed" wheel bearing problems started the minute AFTER the dealership installed the POS Michelin Latitudes (after I -three times- instructed them to sell me and mount LTXs).

IMO, it's the tires. 200k is not "high mileage", unless you have a car. Both my '95 80s have that on them and they're nearly good as new.

Like I said, I put 30k on the truck, after I was told the bearing (RR) was going out. The rear end whines and shakes like a bi*** in heat on some "smooth" road surfaces. I'm putting new rubber on at the end of the summer; I bet that solves the problem.

FWIW, the previous tires were Hankook Ventus ST RH06 (stock size) and were absolutely the best road tire I've ever had. Of course, Hankook stopped making them. I'm currently looking for a similar replacement. If I don't find it, LTXs are going on. The LTX M/S2 (always my first choice for Land Cruisers) is available in 275/50/20 and the Defender (odd that this was supposed to replace the M/S2, permanently) is available in a multitude of sizes.

Do you have the FSM?

The front bearings are cake compared to the rears.

Id be curious to see how long you can keep driving it until you experience any actual failure. Might be ok for quite a long time. The dealer wants as much money from you as possible and will always recommend having work done. My old 4Runner had a bad wheel bearing that seemed to last forever despite what "everyone" said. LCs and 4Rs will keep often keep going despite "imminent failure expected" verdict from stealership.

the good news is that since I didn't buy these whiny latitudes, I don't have to keep them. The bad news is there aren't any rock warriors in my neighborhood. I'm kinda half looking at Tundra 18" wheels as a bridge, but I do not love them. If they get me on the path to a quiet ride it might be a good intermediate step. Craigslist is overrun with the darn things.

This is good to know that it likely isn't bearings and is something as simple as just really crappy tires. For as loud and whiny as they are they should be full on M/Ts. what a horrible designed tire.

I have the techstream CD and cable. They came in today. I have a sacrificial laptop to install them on. I have an ISO of the FSM, and the USB drive for booting is due in later today. Is there a particular page I should go look at?

The MOOG site only had like eight easy steps to the rears - but I doubt it was vehicle specific . . .

Hankook Ventus ST RH 06. In a size up or down . . . https://www.tirerack.com/tires/tire...wall=Blackwall&partnum=755VR0RH06XL&tab=Sizes
but none in 285.50.20

 

[Malleus]

Yeah, that's my prom date too...

those hankooks look a lot like my favorite ever tires for my 1990 rx-7 (sadly not a part of the family anymore). Yokohama AVS db. They were soooo quiet, and actually did fantastic in snow, thought I couldn't explain why or how. Quiet tires are the #1 necessary feature for a convertible, if you believe the top should be down.

 

[Malleus]

Yep. Had one. And Miata. Love 'em both.

I'm working on planting the seeds right now to get a high mpg 3rd car for my commute. It will be a 2 seater. It will have a canvas roof. It will get stunning mpg (compared to the LX)! Sadly for this plan to work I have to sell my current 3rd car, a minty low miles 2005 Acura RL.
