    I used a socket that would just barely slip in the bushing. I wrapped that socket with a layer of duct tape so it wouldn't mar the inside of the new bushing, so the fit was tight (added a tiny bit of gear oil to help slipping it in). On top of this socket I found a socket that was exactly the same diameter of the bushing. I held the two sockets together with a 4 or 5" bolt and a couple of nuts. The larger socket slipped over the smaller socket just a bit so when the smaller one was slipped into the bushing, the larger socket would stop at the bushing surface. I tapped on the head of the bolt to drive the bushing/socket tool in. I'm not gunna lie and tell you that was easy. It really didn't want to go, but once it did, I was able to whack the bolt/socket tool with a dead blow hammer to slide it in. It took a fair amount of force to do so b/c the ECGS bushing's outer diameter is dead-nuts the same size (less a micron) as the bearing race. Make sure you have the bushing installed with the protective "jacket" facing out. On the inboard side of the bushing you'll see both the brass inner metal and the outer silver metal jacket. On the outside you'll only see the silver metal. The "jacket" protects the bushing when you're whacking on it.

    Hope that helps. Trust me, you'll have to whack that new bushing a bunch of times to get it to go. The first 2-3mm of the bushing are the hardest b/c you have to get it lined up in order to make it go. Good luck! Oh, and make sure you put the new oil seal in the right way. I got this side correct, but I think I f-ed up the passenger side (I replaced both CVs and oil seals). Dammit. Guess what I'm doing tonight. I swear I put it in correctly, but some little nagging thing makes me think I didn't. Plus it's leaking. Arg!

    Just to add to the list and my earlier post, Toyota just replaced the needle bearing (under warranty and with a lift) and the "hum"/vibrations are gone (hopefully it holds up)..........now back at the shop that did my rims/tires to see if I can get rid of the wobble/vibrations

    It also helps to keep it in the freezer until install time.

    I had the TSB done a couple weeks ago - the vibe became noticeable after about 15k lifted and 31k on the truck.

    The updated needle bearing has a steel race while the old one was nylon or some other plastic. It should hold up better.

    Interesting and totally makes sense. Which I'd done that before getting it a quarter of the way in. I have a race bearing and seal driver set coming in the mail tomorrow (thanks Amazon) so I'm going to wait till it arrives to pus it the rest of the way in. I have an axle seal coming at the same time so that will happen the same time.

    Any helpful insights for doing the axle seal would be appreciated.

    I'm sure it's posted in here somewhere but, do you have the new part number for the needle bearing?

    I have a 2016 and my dealer won't cover it. If I wanted to pay out of pocket for it, I'd like to have the part number for the new bearing.

    axle seal must be flush with the housing, not driven all the way in. I think I used 2" pvc pipe with a 2" coupling to drive the seal.

    A 2" pvc coupling is perfect for the passenger side seal. Didn't even use any pipe - just tapped on the coupling itself. Viola! (Oh, and I froze it before install)

    If you ordered the same one I did, the smallest driver is too large and will not insert correctly into the new bushing. I roughly machined mine slightly smaller than the bushing.
    The id of the bushing is 1.38 per my hf caliper. The od of the driver is 1.40 before I machined it down.
    I believe if the driver is used as is, it will damage the bushing.
    This is the driver I ordered. https://www.amazon.com/gp/aw/d/B005SMUOR4/ref=yo_ii_img?ie=UTF8&psc=1

    I used a 2" slip to slip, but that ought to do it as well.

    No, that's an inside slip/threaded coupling. Should be the outside slip coupling like the picture I posted below. There's a little rubber lip on the axle seal (well on the passenger side seal anyway) that is almost exactly 2" in diameter so it will slip inside the pvc coupling and the outside ring will make contact with the coupling. That way you are tapping on the whole surface of the seal and not just one side at a time.

    Thanks, I just set up an appointment at ten this morning to get them to take a look at it. Hope they can hear it, sometimes it gets quite after the truck warms up.

    Actually kinda irritated, I just did my 30k service and replaced all the fluids with Redline last week. So they are going to drain out $30 worth of new synthetic fluid and put their crappy conventional oil back in.

    Just wasted my whole morning at the Stealership. They denied my warranty claim saying the bearing has failed because of my lift. I'm pissed.
