DO NOT TIGHTEN YOUR DIFF BOLTS TO 33 LB FT (READ THIS FIRST)

that kit sucks asss and I would never recommend anyone to install it. I had previously installed that kit on my crawler only to remove it later. The quality of the bolts is very poor and stretch over time causing leaks. Plus on top of that the bolts tread from the inside out making it almost impossible to properly torque because each bolt will turn loose every time when tightening the nut.

 

I checked mine today and all were right around 10 ft lbs and I got them all to 18 and plan on leaving it alone until I find time to get it into the dealer.
My VIN is on the list and mine is leaking. I'm thinking I'm going wait till I get the recall letter in the mail and give the dealer time to know what they're doing when these come come in.

 

A stud is the better bet.

 

was it leaking

 

Tack weld a nut on the end of that bolt and remove it,easy peasy.

 

FYI if it makes any difference, 18ftlbs is spec for both 2nd gen 6 lug axles.

Going to check my dads 2016 OR when im over there tonight visiting.

 

Yes. Appears to be leaking quite a bit. I'm going to hold off on taking it in until I get the recall letter in the mail and hope the dealers have a game plan by then.

 

Smart move waiting, dealers not so smart sometimes. I would just make sure to keep on eye on it, it doesn't look critical (soaked/wet) so it should ok till then.
But if they do take down the 3rd member for gasket and new studs, I'd make sure or insist they change the axle seals, I can't make out if they're going to replace them, it sounds like it, but not that clear to me at least.

Good luck!
Cheers!

 

Nope not so easy . It's a stud , pressed in from the inside out, you have to pull the third member press stud out and put a new one in.

 

I'm in charge of Tool's as a collateral in the Coast Guard, just another thing I do beside work on the c130 and fly in it. Anyhow Snap-ons can be WAY out of Cal. Each TQ wrench we have gets sent to the nearest Air Force Base for Calibration checks once a year.
They fail and can be 15 or so pounds out of CAL. Get a torque tester to see if yours is or isnt.

 

Mine looks the same as many others, weeping oil stains.

 

I hadn't noticed any weeping previously and just checked again along with torque on nuts. Still no weeping at 15K and each nut took a light turn to hit 18 lb ft - they were all pretty consistent. My VIN is under the recall so will have Toyota do their check once I get the formal notice. I've been fortunate that my diff is relatively quiet and I did swap out the fluids to Redline

$29 75W-90 Synthetic Gear Lube - 1 Quart (Pack of 2)

75W-90 at just under 9K; the fluids looked in good shape at that time.

 

I have a feeling you're gonna be a happy and trouble free Taco owner for a long time Markc1024.

 

Pop's 2016 TRD OR has 40k miles on it. He changed rear diff oil at under 10k to remove the break in oil.

Stopped by the other day and looked underneath, sure enough there was some weepage of oil around the 3rd member gasket. His vin was NOT included in the recall.

I told him to go by the dealer and get it documented that its weeping a little (no drips but you could see oil spread on the surface) then when the recall does come or he does have problems its been documented.

 

If the fluid level is correct, the fasteners are tight to specs, and the breather valve is correct for application and working correctly, it ought not seep or leak. Seep is PITA and annoying to look at but no harm should come from it, but a leak need to be corrected ASAP.

 

exactly. Neither of us were worried about the small seep. There was no leaking no drips.

That stated my 2013 TRD OR 2nd gen is dry as a whistle on the outside (2nd gen master race )

But he will get it documented just incase.

 

For what it's worth, the recall does not replace the studs or nuts if there is no leak, just tighten to 18 ft-lbs, and call it a day. If there is a leak, further instructions will be coming.

Also, the repair manual states 18 ft-lbs for all 8.0" (BD20D with M8 studs/nuts) differentials and 33 ft-lbs for all 8.8" (BD22A/BD22AN with M10 studs/nuts) differentials (with or without locker). I'm not sure exactly where the information came from that some BD22's used the smaller studs/lower torque value except maybe from the torque value listing in the repair manual that lists all 3 in order but doesn't differentiate (haha) which is which. Generally speaking, I find the lists to be much less useful than looking up the specific components and finding the torque values listed there.

It would seem to me that the recall is only for automatic trucks without differential lock, based on the torque value that the recall instructions give.

Actually on 2005-2015, models without diff lock had 33 ft-lbs, models with diff lock used 18 ft-lbs.

The studs are not pressed in, they are double-threaded studs. They can easily be removed from the housing.

Exactly, it sucks for a new vehicle but it doesnt seem major and it's good that Toyota is taking care of it. I had an older, higher mileage ford that actually dripped for a long time with no issue.

I know one thread where a diff immediately failed started with "I saw a huge puddle of oil under the truck."

These are just seeping a little bit for the time being. Drive down the highway and look at the diffs on other trucks on the road, more often than not you will see them soaked.

I think most people are safe until they can get to the dealer for verification.

 

Wrong. (FYI THIS IS FOR A 2005-2015 REAR DIFF WITH LOCKER.... NOT A 3RD GEN)




FYI. I did notice the stud size on my 2nd gen was smaller (m8 w/ 12mm nuts) vs the stud size on my dads 3rd gen TRD OR auto (m10 w/ 14mm nuts).


Should the large stud / nuts be torqued to 33ftlbs or 18ftlbs? Also where the hell are people getting the 33ftlb spec?

 

My mistake, typo. For 2005-2015, without diff lock is 33 ft-lb, with diff lock is 18 ft-lb. For 2016-2017 A/T without diff lock is 18 ft-lb, M/T and A/T with diff lock is 33 ft-lb.

33 ft-lb. As for where, I am looking it up in the repair manuals. I checked 2005, 2015, 2016 and 2017 repair manuals on TIS.
