    Welp, I got a little vibration between 20 and 45 mph. Here's the story so far, and what I'm doing next...

    Got the runner a few weeks ago and threw on Toytec's 3" Bilsten lift as well as some Total Chaos UCAs. I noticed the vibes right after the install. These vibrations are similar to the growl that you get from a set of agressive MT tires. I'm still on the factory wheels and tires. The vibrations go away when shifted into 4Hi. I didn't drive it again until it went in for an alignment. The alignment didn't make it better.
    After some research on TW, it seems that the Tacoma guys have dealt with the exact same issue. I guess its a diff needle bearing on the driver's side that's experiencing too much radial load due to the increased angle of the CV shaft. The fix (for some) is to swap the needle bearing out for a bushing. So I went on the ECGS website, out came the credit card, and now I'm waiting for the bushing kit to ship to me. It doesn't seem like a huge chore, but I was kinda hoping that someone on here has done this job on a T4R and could offer a little advise. Thanks in advance.

    its hit and miss for the runner some say they have the issue (myself included) other no problem. the fix goes all over too. 4 some its aftermarket wheels some say diff spacer. others have done road force balancing and wheel has to be balanced with back spacing flange. mine never really went away but the road force helped. for me it's so nominal that I can take it or leave. best of luck with yours

    Ecgs took care of my problem on my 16 Tacoma after I lifted it. Getting the tool in was hard. I had to shave a tiny bit off one side so I could slip it in between, you’ll see what I mean when you do it. Make sure you get out a complete bearing. Had a couple pieces break off. Stick a grocery bag in the diff, worked for me. When you put the sleeve in make sure it’s straight before you start pounding on it. Rent a bearing install kit if you don’t have one.

    ECGS bushing took care of my vibes on my Tacoma. I had no issue with my 4Runner though. I think I still have the special tool, if you are interested shoot me a PM.

    Success! The bushing is in and the vibes are gone. The install went smooth and without issue. Well, there was that fireant that crawled up my pants and bit the back of my sack, but other than that, perfect. If you look at the bearing, it's pretty easy to see that the shaft was actually riding on the cage as well as the rollers. Kind of a shit design if you ask me. I'm glad I didn't ignore it.
    Another thing was that my front diff was way low on fluid despite it having the factory paint marks on the plugs. Less than a qt. came out and a little more than 1.5qts went in.
    Thanks for all the advice, everyone. It really helped!
    :yes:

    thanks for your posting on this .. great info.. @3K miles I did inspect all the fluids .. all looked perfect except for the rear diff..
    many do get the free oil changes , but many dealerships do NOT inspect all the drive train fluids ...so with low diff oil that would damage the bearing ..

    For sure. I have pretty long road trip coming up this week. Some 2000 miles round trip. I'll check back if anything pops up.

    The plastic bag is an excellent tip. I was lucky enough to get the bearing out in one piece, but I would have definitely been frustrated had I lost some shrapnel into the diff.

    I'm about 60% into my road trip and have covered around 1200 miles. From Southeastern New Mexico, visiting some good friends in Phoenix, then a long weekend in LA and game 3 of the NLCS, and now Im visiting my Mom in Porterville, CA.
    The 4runner has been running great. No vibrations or oil leaks. So far so good. My only minor complaint is that the suspension is a bit stiff for LA's 100 year old freeways. Maybe if I could drive them faster than 7mph, then the suspension would have soaked up the potholes better.
    All together I'm happy.

    It is a poor design imo. I don't know why they don't just use one like the ecgs. Must be a good reason, though.
