Is the rear end howl only on 4x4 models or 2wd as well?

Are the 2wd models affected? Anyone with a 2wd have the howl?

 

Anyone?

 

All of them can howl. Its the rear diff that causes the howl so 4x4 or not does not matter.

 

Yea I was wondering why the tsb for the 16 and 17's only covered 4wd models?

 

Huh, never noticed that it specified 4x4 models, but thats what it says.

 

Yep does yours howl being an 18?

 

Yeah, mine howls. I just had a TFS look at it Thursday. 3rd time I’ve taken it in for the howl. No luck being my truck is a 2018 and a SR5. Dealer said he would issue some reports to Toyota this time to try to get them to fix non TSB Tacoma’s. I may end up fixing it myself. I have a long bed so I wouldn’t need new springs at the least.

 

OK. Hopefully they'll expand the tsb to the 18's. You'd think they would already apply it at production.

 

is this another quirky issue that has arrived?

 

Nope one that has been around just curious if 2wd models have it.

 

got it, so add the howl to the list of issues, trans shift games, and atkinson dog engine. Got it! Ill have to read on this now

 

They may do that eventually, but I am not sure how that all works. The TSB came out in February which was 2 months after my 2018 was built. Maybe newer 2018's will have it? I doubt it though since its not a safety issue.

 

I think TSBs like this one are pretty much only for vehicles they list that exhibit the issue.

 

Not sure, probably after enough 18 owners bring it up. They may do it on the March on builds.

 

Yeah, that seems to be true. I knew I should have bought an Off Road...haha

 

They still haven't even extended the TSB to the rest of the 2016-2017 Tacomas (AC and non TRDs) so I doubt any 2018's will see it any time soon. I'm going to see if my local dealer will cut me a deal on the parts this week. He said he is really interested to know if the TSB would fix non-TSBs and is a pretty good guy. You never know!

 

Do the 2WD's have the 8.75 rear diff? That's one of the qualifiers for that TSB.

 

I don't think they do, but I'm not sure. Yea trazerr if you install the parts let us know if it works!

 

I think they can? You can get a 2wd Off Road with locker and the diff with the locker is an 8.75, correct?

 

Will do! I'd rather not spend the $$, but I am really curious myself. I am 99% it will help out a lot just like it does on the TRD's. I got the tools, time, and the shop to do it. Now I have to decide if I want to spend the money ha
