Backing Plates

I don't think they make drums. I didn't find any on their site but that'd be dope if I'm missing it.

 

I finally got to it a week or so ago. Definitely not bad to change out, just didn't want to walk into any sneaky issues if I could help it so I started this thread. Maybe this will help someone in the future or at least answer some questions.

To change the backing plate, obviously you have to do a number of things; drain the diff, remove the axle shaft, have a press and special adapter or make an adapter to take off the ABS Wheel, remove the spacer, remove the C clamp, press the shaft through to seperate it from the backing plate, remove the other spacer, remove the bearing from the bearing housing then you're pretty much there. Most videos end here online then start the rebuild with a new bearing and seals. If you're replacing the backing plate, this is the final couple steps. The studs that are in the wheel bearing are holding it to the backing plate. Thread a nut onto each of the studs only far enough to get it flush with the top of the bolt inorder to not mushroom the threads. Take a hammer and a brass dowel (preferably) and tap out the bolts. They're grooved or splined, however you'd like to name it, so it'll take some whacks. Onces the bolts are out you should be able to knock out the bearing housing or it might just fall out. Then reverse for install.

Wayyy easy. I started this project with fixing my parking break and ended up replacing all axle seals, break hardware, shoes, plates, drums and of course some fresh 85w-90 gear oil. Took two days from start to finish working most of the day on it.

Put a few hundred miles on it since then and no issues.

Now the front end

 

I wrote that post then the next day a problem arises. A noise coming from the right rear that is almost like a creaking noise or a rubber slipping on metal noise. It happens with every tire rotation but not during the entire rotation. I applied brake no change. Same with the parking brake, no change. I then put it on stands, put it in neutral, spun the tires, no noise. I put it in gear, the wheels spun, no noise even when appying brake and parking brake. Put it back in the ground and the noise is there immediately when i start to move so its only when theres a weight on the wheels.

I don't have the press anymore because it was borrowed and I have family coming next weekend for our wedding. Then I have surgery after that with a long recovery. So this is not the best timing.

I know the correct answer is drain the diff and pull the shaft. That way I'd find out if it's the oil seal or the bearing. But i dont have the parts to replace it so in a way, its not helpful. Quite unfortunate. Before anyone says it, yes, all seals and bearings were OEM because I didn't want to do this again.

Anyone run into this before?

This is the sound.

 

thats a weird one, yeah it kinda sounds like rubber rubbing metal. I dont see anything that would make that sound though except for a dry seal. Did you leave the axle shaft seals dry or did they come with a little grease between the two lips? I have always put a little grease between the two lips of every double lip oil seal to keep the lips from drying out, even though i know how the oil lips work and how they create their seal. If you dig into it, the inner lip against the oil, seals the oil in by creating a meniscus of oil between the tip of the lip and the shaft, this keeps the lip from actually dragging the steel shaft as well. The outer lip is simply to keep dirt and sand out and away from the inner lip. This is another reason i normally put grease between the two lips, it helps aid in keeping dirt and grit out of the inner lip and also keeps the outer lip from being dry and rubbing the shaft.

 

How's the rubber around the carrier bearing, front and back?

Does it persist if you apply the parking brake and release it several times?

 

@badass03taco I did put some grease on both sides during the install. If it went wrong grease wise, it wouldn't surprise me for the reason that was the most aggravating part of this entire job. I took it in out a number of times trying to tap it in there evenly. In the process I might've rubbed the grease off with my hands because once it got in there all I could think was "thank God that's over" rather than verifying every thing was still lubed. I hope that's what it is better that having to reaccomplish the whole bearing process.

@shifty` the carrier bearing is new new. Still shiny. It was done right before I bought it. The last tundra I had that that similar squeak that turned out to be the carrier but this is just a tad different. Having all the windows down and driving slow with privacy fences on both sides to bounce back the noise, it's a lot louder on the right side. As for the parking brakes, I tried it in combo with the regular brakes and solo. No change for either. I do though have another problem with the self adjuster not adjusting when I apply the parking brake. Not sure if the new metal lever locking piece is just bent enough to not do its job or what. But I'll dive into that another day. I don't think it correlates. I wish it was a brake issue but it doesn't seem to change when applied.

The biggest standout in the trouble shooting is I can only replicate it with a load. That makes me look towards the bearing but I really hope it's something where I don't have to find a press again.

 

You sure the carrier wasn't installed backwards?

It's pretty easy to rule out a wheel bearing. Also easy to check u-joints.

 

It might've been installed backwards, not sure. What's the best way to tell? It's odd though it's now appearing after the rear end job. What's your go to way to trouble a possibly noisy bearing?

 

Ah, wait. I think I was confusing this post with another post. Dammit.

Yeah, not sure on that one. It's weird. It'd help if I recognized the sound, but it doesn't sound like any noise I've heard before...

 

So, just to update. I've come to the conclusion that the wheel bearings I bought from partsouq.com were possibly old or something. They were OEM. Packaging and the bearing it self, looked the par. I bought a new bearing from the dealership and reaccomplished the passenger side. I want to note that the bearing I got from the dealership looked identical to the partsouq.com one. After install, the noise went away. But the funny thing about it..the drivers side began to make the same noise as the passenger side, two days later. That's when I thought, it's either a poor install or bad part. It's been over double the milage since the original install and the passenger side hasn't started again. I came to the conclusion that it was bad from supply, somehow. Still holding out a while longer before I do the drivers side just to be sure.

So, if anyone runs into a squeaky, rubbery repetitive sound coming from one side of your vehicle towards the rear like the video above, I bet it's your wheel bearing.

If you have any questions about doing a rear wheel bearing, lmk. I'm getting some good experience lol.
