2018 leaking rear diff

As a volunteer Sheriff’s Deputy I’ve been doing surveillance for years. One time I suspected an ex-girlfriend of mine of cheating on me, so I tailed her for six nights straight. Turns out… she was. With a couple of guys actually, so… mystery solved.

 

Well that's one way to discover your passion for law enforcement.

 

While we are on the conversation of my truck what’s all this crap on my frame? Saw it while looking at the diff.

 

Well that will put a damper on a relationship

 

Seam-sealant. All good.

 

I just dealt with this... My dealer took care of it with no issues. Gave me a rental for the day.

 

I think mines is like that. Have to tell them next time.

 

It was seeping through pretty badly

 

Yea HINO makes a bunch of Tundra and Sequoia parts. I believe the manufacture the entire rear Tundra axle.

 

The number of chicken littles this site attracts is phenomenal. I have 2018, same small weep spots after a couple thousand miles. Mentioned it to the dealer at my check up, they retorqued the bolts and cleaned of the diff. 6000 miles later and no signs of seeps, even after I did the breather mod.

At your next check up, make note of it to the dealer. They will likely do the same thing they did to mine. No need to rush to the dealer or make a separate trip unless diff fluid is leaking on the ground. If the spots are diff fluid, the amount that has seeped out is insignificant. The issues for the 2016/2017 models consisted of significant amounts of diff fluid leaking out, which eventually led to the diff seizing up.

PDF A510-D also includes pictures. My dealer retorqued the bolts and it been fine.

 

Damn right I would take it in. If it's an 18 with only that many miles then they need to make it right.
I myself would check torque on the nuts and make sure they're not loose. If they are loose I would change oil and flush then reseal it then fill with oil. I do it at work on tractors and log trucks so ain't scared to. however it's NEW. They should fix!

 

Mine was also sleeping around 10T miles ago. Cleaned it well and it never returned 11T miles later.

 

Could have a stressed stud. Didn't the recall include new studs and nuts also?

 

Pulled up as the service department was opening this morning. The tech leaned over and looked it it. We walked inside. Sent me over and I got a 2019 Camry loaner. They are replacing the gasket and nuts per the safety recall H0G. Pretty easy experience thursfar.

 

I have heard that here before. That is not a thing. I don't care what the issue is and if the car with catch fire and kill everyone on the highway 5 miles out, they CANNOT keep your vehicle against your wishes period.


Edit: Not trying to sound confrontational, just want everyone to be aware that this is not legal at any mechanic.

 

Checked my diff and looks just like the OP's except not as 'wet'. Made in Thailand. Will mention it to the dealer at my 10K service. Good catch, thanks all!

 

Actually they can. I had a car years ago that got quarantined for leaking gas tank. Rust spot at the straps developed a very small hole & started leaking. Kinda different situation considering the flammability difference but it happened. They wouldn't let it leave the shop until fixed. I might have been able to sign a waiver & fix it myself but I just let them do it

 

Just got my truck back. That was quick. New gasket, new bots, new fluids, and cleaned my diff off.

 

Good deal man. Just keep an eye on it...
