Your character and loyalty are top notch my friend.
Though I’ve got to think Chevy dealers throughout the country are a little nervous...

I dont like the headlights on either truck. The rest is okay, but the headlights on both the Ford and Chevy are butt ugly.

Thanks buddy

Yes ..Absolutely nervous ... Ok let’s accessorize it.

Considering most automakers take each other’s style and market popularity ....it appears the GM and Ford designers went Rogue in their front ends.

As I see all the other features apear in each model

Chevforyotodge.?? . Ok I’m putting the vodka away

Well on the positive side, the snow plow does cover up most of it. I would call that a successful accessory.

Nothing could be worse than when Dodge introduced the first truck with a grood. You want to talk about something butt ugly and even worse when the hood's open. LOL At least the Chevy still has a distinct grill and hood, not a grood.

How about this. You'd have to add one heck of drop hitch.

Trifecta bf220! Forgot about that. Nice post.

Well,

I got the truck back today and the shop couldn't find anything to justify tearing down the differential. They confirmed a slight gear whine as I told them, but in their opinion, it was extremely slight and not significant enough to warrant a /teardown/rebuild at this time. I was advised to keep an ear on it. It is entirely possible that I am overly sensitive to sounds on a vehicle as I tend to be OCD when it comes to maintenance. I can actually tell when my tires are off by as little as 1 pound in the way the truck handles. I also still change my full synthetic oil every 3k when towing. I only started going to 5k on oil changes about a year ago on the other cars (all full synthetic and yes, I know, overkill, but that's me).

A little frustrating, but I'll have to try not to worry about it for now. They did offer a couple insights--the ring & pinion is very heavy duty, especially for an SUV (I think it is shared with the Tundra). No one that they know of rebuilds Toyota R&P's, so you are looking at a new one. No one really makes an aftermarket for the Sequoia in that gear range, so if it's necessary to replace some day, I would have to go with a Toyota OEM part. I haven't really looked, so I can't say.

They did recommend switching to a heavier gear oil since I am towing. Factory calls for 75w85 and they recommended 75w90 or 75w140, which seems pretty thick for the cold up here. They are am Amsoil dealer, so they recommended that. I know some that love it and some say it's snake oil.

So who knows...

Fun fact - Amsoil doesn't make a 75w85 gear oil. Can't imagine why an Amsoil dealer would recommend 75w90 - which they do make. Weird. Here is what Toyota has to say about gear oil, no mention of different weights /w towing.

I would run the OEM fill and change it per the Toyota Schedule. Maintenance schedule for the Sequoia says Rear Diff Fluid Every 15k which seems crazy to me, but diff fluid is cheap, just do it every 3rd oil change.

Funner Fact: The only 3 gear oils that I have come across in that weight are Redline, Valvoline Synthgear, and Toyota...and I don't think the Valvoline product has been around that long....so, it makes you wonder who produces for Toyota. There may be others, but I haven't seen them. I've always been a Mobil 1 guy, but they don't have it and I do totally agree with your callout about Amsoil weights....probably a little too coincidental. If I remember, the Toyota OEM fluid is about $31/quart....not cheap.

As for the interval, I've always done 30k on this truck which is what is called for unless towing, then it's 15k as you stated. So far, I'm 10k into the last fluid change since I changed just before I started towing, so well within "parameters".

Oh well...all fun and games I guess.

Huh - guess you are right, I didn't realize 75-85 was so rare, but come to think of it about everything else I can think of does use 75-90. I worked for Valvoline for about 8 years, the guys that developed SynPower were a couple buildings over, they claim it was good oil - they seemed really smart I went /w it.

Quick google search points to 75-85 being developed to help /w fuel efficiency. Stupid EPA.

Ding ding ding....all about mileage

I was a valvoline guy until I lost my expedition engine at 35k using it

Good news ? Kinda?

If it’s not correctable at this time we will just have to see if it increased when your under load.

The drive side of the Ring gear is where the wear starts to show. The “Howl” you hear is the pattern on the drive side changing toward the edge. 40 Mph and up with on and off throttle only on the acel side is the pattern just wearing away from its original location.

As long as the howl seems limited at a certain speeds they may not be able or want to change it as it so slight.

No worries pal at least you had it checked and it was blessed to continue. Continue with OE oil ( don’t overthink what Toyota has proven) and keep that rear end ( axels) out of the water when launching .

Here a quick diagram if they haven’t shown you already.

[sailor55330]

Thanks CJmatt.

Yes, that's what I was told. They also were very open that they just didn't think it warranted a teardown and rebuild as they could barely detect it (but they did with a stethescope on the rack finally). It's a mixed bag. It bugs me, but it's been blessed, so I keep an ear on it and see what happens for now. It is very limited between 49and 60 mph under load. I expect it will get worse over time, but all I can do for now is be attentive and keep up with the fluids.
As I said, the shop has a great reputation as they specialize in 4x4 driveline work, especially building trucks for off road and rock crawling, so they know drivelines pretty well. And yes, I keep the rear end out of the water. Heck, I've only ever had the rear wheels wet once, let alone the diff.

Thanks again to all for the advice.
