OFFICIAL 2nd gen 4x4 front differential bearing vibration thread

Huh well that's a snap - it does NOT go away in 4Hi, so I'm assuming driver's side wheel bearing--is that a safe assumption?

 

Possibly, jack up truck, put on jack stands, shake wheel up and down, if there's movement, bad bearing. Also spin it, if you hear screeching or rumbling, bad bearing. Don't be fooled by brake drag though.

 

Thanks - will give that a go here. Local shop quoted me $420 out the door for a wheel bearing replacement. I think 155,000+ miles isn't bad for a wheel bearing

 

texoma advice is rite on money. have had bad wheel bearings on other trucks. movement when jackd off ground and noise when tire is spun

 

There are two different guys on here that make the wheel assembly. Around 200$
@nj636 or @BamaToy1997

 

For both sides? re-using the hub, bolts and o-ring? Are they going to replace the cv dust seal that is likely damaged for $420?

 

For just one? That is just crazy! You can buy one of my complete assemblies with all brand new parts for $165 each right now, and do it in your own driveway if you wanted, saving tons on labor costs!

 

Anyone near Ventura California with the removal and install tools? I'm ordering the bushing come Monday.

 

I did the ecgs bushing last weekend. Replaced rough country lift with 2017 off road shocks and springs. Toyota replaced leaf packs this week. Truck rides a lot better. Original front bearings but have two bamaboy complete bearings in garage. I have a little slack in stearing and what seems like tire noise to me. Have jacked up front tires and no movement or growling sound.

 

I may be late to the game here, but my 09 dcsb sport has this issue, since lifted at 22k, now has 43k, had the extended warranty for 8 years, ran out a year ago or so, is the TSB free? or just under warranty? They did the AAL's and steering bushing thing for free. Anyone have any recent stories on costs?

 

I’ve got 6 K+ miles on my dealer installed TSB needle bearings. Still quiet as a mouse (5100s at 1.75”)

 

So is the general recommendation to do the TSB and if that doesnt work do the ecgs bushing or just go straight to the bushing?

 

For $60, I'd just do the bushing instead of having to deal with the headache.

 

To me the headache would be getting the bushing installed. The dealership hooked me up under warranty with no muss, no fuss.

If it does come back I’ll do the bushing.

 

Yeah Im tempted to let the dealer do it too. But having to take it there in the morning, get a shuttle ride back home, wait a full day for them to fix it then get a ride back over there is turning me off to the idea when I can knock it out in an hour or two and not have it affect my entire day.

 

Right on!!

 

But yeah its Toyotas bad design so I also feel they should be taking the hit for it.

 

Got my bushing and seal today... anyone got a removal tool to loan or sell? I'm in Ventura, Ca...

 

Hey everyone, new guy here. I came across this thread because I've had the same issues and it seems like I may be having it again. Bought the truck Certified pre owned in July 2017 with 22k miles. In January 2018 I took the truck in for a vibration at 28k miles. They performed TSB 0026-15 (FRONT DIFF GROANING/GRINDING CYCLICAL). Replaced needle bearing, seal, and a few other parts associated with it. Now at 30k miles the same rotational noise is back but slightly less severe at before the TSB. Dealer documented noise and tried for a few hours to find a specific cause, but no luck. They said they would call Toyota techs Monday to see where to go from here. Just thought I would add my experience to this thread since it seemed to be pretty active still.

 

It' crazy how soon these become problematic, just did mine last weekend on my 2013 with just under 45k. That ecgs bushing makes a world of difference.
