Using Lexus Front Differential Fill and Drain plugs

I was planning to change the front differential fluid in my '04 Tundra SR5 DC 4WD.
Has anyone used the Lexus hex head bolts instead of the Toyota allen keyed bolts for the drain and fill?
I'd rather have the hex head bolts if they are compatible, since the allen keyed are more prone to strip.
I'm reading other posts that are saying the Lexus parts fit the Tundra, but they are installing them on later generation Tundras.
I want to know if anyone has used the Lexus parts on a Gen1?
The Lexus part# are 90341-78060 fill and 90341-24013 drain.
Thanks.

 

Yes, we've used those. Others have as well. You already have the part numbers, but here they are again anyways because I searched through my emails for this, and I'll be damned if I don't post it.

90341-24016 Plug Straight Screw
90341-18060 Plug Straight Screw

 

You did, right here, but it's an image, so there's no text to search out.

But it was also posted and discussed over here:

And probably in a few other places I'm too lazy to link

 

Thanks for the confirmation!

 

Damn that one thing was in OCTOBER????

 

Got ‘em. Haven’t used ‘em.

 

I shoulda bought 'em for the front diff, but I was impatient and pre-checked my plugs, both popped free with limited effort, so I figured "maybe next time".

I now wish I'd have replaced both front plugs and all 6 washers, but hindsight is 20/20 I guess.

Knowing my luck it'd have turned out like my blower motor resistor today. Ordered from local dealership 25mins away. They told me it'd arrive first thing this morning. Drive all the way there just to have the guy tell me, "Oh shit. So... about that ... the truck delivered our crate of parts to the wrong store today, so it won't be here 'til tomorrow"

Like. "Damn. Thanks bro. I guess I'll drive my 30 minutes home, and 30 minutes back on Friday, with only HI speed on my fan? Didn't you think to call anyone, after we sat and shot the shit for 10 minutes about trucks while ordering yesterday? It's not like my number isn't in the system and I told you I'd be driving all this way tomorrow, because you said it'd 100% be here at 6am, right?!"

And here I was trying to find a new dealership to deal with, since the one I'd been going to is under new ownership and dropped out of the national Toyota Parts program...

 

Not to worry, if I get mine off without stripping, you shouldn’t have an issue. Lots of penetrating fluid and patience.

 

Oh, I finished mine last month.

 

PIA?

 

Nah. But I see the potential for them to get frozen. Once the housing's alloy gets seriously broken down, as it does with salt and such, knowing how much steel and alloy love to fuse together, I can see such a bonding reaction happen. Add into that Toyota's genius idea to use an allenhead, granted with a 'safety net' torx connector beyond that in case you strip the allenhead provision, and you have a recipe for potential problems.

I have a really good twist-head allenhead socket set that I tend to favor on stuff like this, but someone going in without care, not realizing any care could be needed ... or maybe their front diff has never been serviced and they live up north ... I could see that being disastrous.

 

Would a light coat of anti seize on the plug threads and underside of flange be something to consider?

 

If you live in road salt areas, it's not going to kill anything. Just beware of over-tightening with that extra lube there. Same risk as with spark plugs and anti-sieze.

 

Couldn’t hurt. For the longest time I just bought new plugs/gaskets with every change of the front diff so I didn’t have to be concerned too much about rust buildup. Works so long as you don’t wait too many miles in between changes.

 

I am switching over to the lexus drain plugs. Would the torque specs for the lexus plugs be the same as the stock toyota plug torque specs?

48 ft lbs for drain plug
29 ft lbs for fill plug

Thanks!

 

yes, if the lexus plugs can handle more, theres no reason to subject the housing to extra stress... but if the lexus spec is lower, might wanna go with that to keep from hurting the plugs.

 

dont have a lexus dealer with in 300 miles. Napa can get dorman drain plug in 2 days...#991000 but cant find a dorman/napa # for the fill

also part of the reason I was looking at napa, is all the online lexus dealers want an arm and a leg to ship to alaska ( or hawaii) or have a 10 day ship time, and i kind of need sooner
