Rear End Recall and changing fluid?

Okay took my truck in for the recall yesterday, they tightened the bolts, yes tightened with what looked like a Mileaukee inpact driver. I was at window where I could watch them about 25 feet away. That being said was planning to change the rear oil fluid over to Amsoil syn. With the known promblems with the rear ends leaking would you? Could they use this as a reason to void warranty on the rear end if future problems of leaking or broken studs resurface?

 

Amazing they used an impact driver, not a torque wrench.

Did you happen to take a pic of them doing that?

 

My opinion...
It has to be proven it caused the failure.
This doesn't mean they won't initially deny you; nor, does it mean you would win or lose during arbitration.
As long as it meets the spec; you should be gtg. If Toyota claims only their oil meets the spec, they should be providing it free, at the scheduled service interval.
FWIW, I'm using Redline 75w-85.

 

Personally....I would lay low for a bit until this blows over. If Toyota decides to expand this campaign....i.e. replace the studs or upgrade the gasket, etc....you've pissed away your money. The OE fluid is perfectly fine for the time being

 

i was looking at redline to just was feeling safer with amsoil for some reason, but is the wt. of the oil......is a lighter oil then toyota recommends. but both are GL-5 rated.

 

Countless rigs with 200k miles on OE fluid that's never been changed. Just sayin'....

 

Okay, was just looking, Redline makes 2 types of fluid that is 75w90, one for limited slipped and one without......If am right i should be able to use the one for non limited slipped since the LSD is brake controlled on the 2017 tacoma's, .....am I right?

 

Yes

 

This for sure.

Amsoil especially is not cheap. This diff thing is clearly snowballing even over the initial scope. Don't spend the time or money on the diff fluid yet if you need to go back in and have them drain it for whatever reason there may be.

Don't worry so much about warranty either as the average tech won't know the difference between aftermarket and oem fluid.

That said, once the campaign as settled down, definitely change your diff fluid. Mine looked like shit (https://www.tacomaworld.com/threads...-manual-transmission-6mt-fluid-change.481719/) and I wouldn't have wanted to keep it going for longer than I did (10k miles).

OA

 

okay, since rear end has been taken care of, order 4 qt. of amsoil 75w90. as perfered member, was 12.00 per qt, which is not to bad......

 

^^This^^

And ^^this^^ believe it or not is true.

Cheers!

 

I have no doubt that the OEM fill will last a long time but, I decided to change mine after seeing the metal collected on the magnet plug when others drained theirs. I have less than 14,000 miles and I too found a lot of metal on the magnet. OEM fill would probably have lasted a for many years, but for less than $40 for the oil and 15 minutes of time, I think it is worth it: especially if you keep vehicles forever like I do.

Also drained the transmission oil and replaced with Redline MT-90. Again, found lots of metal on the magnet, but most importantly, the shift is much, much smoother.

 

Nothing wrong with that. But given the OP's circumstances with his 3G rig, I'd wait it out a bit so I didn't waste money if the campaign expands.

BTW...some metal in the diff is normal. Also...if you drained your new fluid, it's likely you'd still find some metal in it as well

 

Already ordered my Amsoil Severe Gear for both front and rear ends; along with Signature Series oil, EA Filter, PI gas additive, and gasket set on Amazon yesterday. Taking it in this week to get 15k service and my standard 5k oil change. Going to have them change the front and rear end fluid on my dime, and also have them take a look at the rear end, as I'm having some weeping... Will try and insist the gasket gets changed (via warranty) beyond just torquing the bolts, especially since I'm paying for them to service the rear end while it's there.

Called service manager last week, said he had no problems changing out front & rear end fluids, but advised against changing out the transmission fluid to a aftermarket fluid... Said Toyota is very particular about their transmission fuild when it comes to warranty; said he would check the level though... Ok no problem.

Also wanted to find a equivalent to the transfer case fuild, but no one really makes one yet, as Toyota has kept this fuild specs proprietary for the time being... Figure I'll just stick with stock for now, and change at the proper service interval.

Also going to leave it there for the required 6 hours (for cool down), and have them properly check/fill the transmission level.

Oh, and also having them change out the oil drain plug for a fumoto valve as well, to make drains easier with the pro skid plate.

 

I would ask for the empty Amsoil bottles. But I'm not a trusting person.

Also....if they determine your rig needs some diff work beyond just the torquing of the nuts and it turns out it's going to sit around for a couple of weeks waiting on parts....I'd find away to be present when they refill the diff. It's likely they won't remember and will fill it with factory juice.

Better yet. Let them do whatever they want with the diff. Then once you're good to go....change it yourself at home.

 

Not on the recall, so most they'd have to do is order the diff gasket, in which case I'll bring it back the next day. Even if I was on the recall, they wouldn't keep my truck... Shit don't fly in my book.

Anyway, yeah I always stand right outside the service area, and watch them do the service (yep I'm that guy) and then thank them personally. As it will have to be at the dealership the entire day for transmission fuild check, I'll ask for the empties back... Good idea.

Also, would tend to think if they used their factory fluid instead of mine, they'd charge me more... All I'm paying for is labor costs.

 

ACDelco makes a cordless torque/impact wrench (model ARI2060) that has a 6-stage digital clutch (60, 80, 120, 160, 220 and 500 lb·ft)--it's pretty neat a friend in Daytona has one in his racing shop and uses it all the time. Reviewers have said it's very accurate.

It costs around $400. I imagine others make similar tools, but the ACDelco looks kind of like a Milwaukee tool. Thing is though that even the lowest setting is far too high for the carrier fasteners--maybe there's a smaller model too?



Answered my own question, there is a 3/8" drive version with settings of 15, 22, 33, 41, 52 and 80 lb·ft settings; and a 3/8" angle drive version with similar settings.

 

thanks cliffyk.....it does look like that.....thanks a lot, makes me feel better now, again thank you

 

75w-85 is the Spec Toyota calls for.
