Help me solve my vibration issue!

[izzy]

I have the same exact tires on Toyota wheels. Is the vehicle lifted? If lifted over 2.5" with any type of lift, it could cause a needle bearing issue. BUT, only when driving slow or coasting at 35-40 mph. On my lifted 3rd gen I had that issue between 35-40 mph and never fixed in the five years I owned it. Never had an issue, I just got used to it.

Before throwing down on a needle bearing install $$$, I recommend a good road force balance and an alignment. Get the road force balance at Discount Tire; they guarantee their work, and I recommend an alignment at a Toyota Dealer since they do a lot of them on your vehicle.

No lift, I don't have the TRD wheels anymore just on OE steelies and it all balanced really well with the BFGs. I had my independent shop do that though, they take their time.

Maybe OP and I have two different issues tbh but idk.

A cooked rotor would be visually obvious too.

Frozen tires?

I have a vibration issue I've been chasing. Seems to be less noticeable if I park in the garage or after tires warm up.

The truck hasn't seen freezing conditions yet this year. Good idea though.

Note: balancing is hit or miss; they may have slung a weight. As for alignment, if you brushed a curb or did any off roading on rocky trails that could have messed up the new alignment, curbs especially. I would take it to another shop and have them re-balance the wheels/tires. Other than that, if you live in the mountains or haul anything, long or hard braking can warp the rotors. While rare on Toyotas it does happen and will vibrate under braking, say exiting the highway at high speeds etc. The dealer should cover that under warranty. I doubt it is the drive shaft on this new gen, but I will tell you running 35psi with c rated tires in the morning makes the Tacoma ride rough, especially compared to the 25 4runner SR5 we have with the same tires.

There's no change while braking, and I've warped a few rotors in the past and know that feeling. It's actually most noticable while not braking (mostly on coasting/decel and consistent speed).

The vibration came on quickly and didn't change when I swapped back to my OEM wheels and tires. I'm certain that it's not a tire or wheel issue.

Make an appointment and drop by the dealer; no other solution, and it is under warranty.

Maybe the beginning of a bad wheel bearing?? Definitely weird! Usually you can tell pretty easy if it is. But maybe?

That's happening tomorrow.

I had to open a case with Corporate Toyota, since a dealer tech initially brushed it off and said "it's a truck, it's not supposed to drive smoothly".

My faith in the dealership isn't high so I'm also trying to troubleshoot myself as much as possible.

I had that thought too.

There's no obvious play in the rear wheels, but a rumbly bearing might be an issue.

Oh cool, that is a great idea.

I checked the price though...... $99.99!?!?!?

They need to offer a consumer (not pro) version for like $10.

You just post on TW? I see you have a long bed, is there a carrier bearing with the longer driveline, or 2 piece drive line? If yes that would be the first thing I’d be suspicious of.

I believe @Gfenza89 has this exact issue

Yeah, I posted on TW as well to try for more input.

And yes, longbed with a carrier bearing. That's another possibility.

I downloaded some free vibration analyzer software and just did my own calcs to determine the rotating frequencies for the diff and drive shaft. I'm going to test that after work today.

His trans was the issue, right?

I have that fear for my truck too.
