Transfer case fill/drain torque specs

[mooockie]

I tried searching fo the write up on changing fluids in diffs/transfer case, but couldn't find it. I think I remember specs of 28 ft-lbs for the tranfer case fill / drain plugs. Anyone know?

The ONLY time I ever use a torque wrench is when I'm bolting a head back. For this bolt..just do it snug using a 3/8 ratchet.

Yeah, that's true for most things, but for these plugs a torque wrench is essential, especially for the front diff drain plug. You need a 10mm hex bit to get it off, and if the thing is turned too tight it is near impossible to get off without rounding off the inside of the hex head. Don't ask me how I know. Oh, same for the front diff fill plug.

From my Haynes manual for 03-09 T4Rs ...

Transfer case filler plug and drain plug = 27 ft-lbs.

Front differential (4WD models) fill/drain plug = 29 ft-lbs.

Rear differential fill/drain plug = 36 ft-lbs.

I replaced the fluid in my differentials. I did NOT use a torque wrench and never had a problem.

That's nice, and your response had nothing to do with the question. Good for him doing things the CORRECT way..

Have you ever worked on a vehicle before.

I've yet to see any experience mechanic that would use a torque wrench for this.....Every single bolt on every car has torque specifications. Even spark plugs. Do you use your torque wrench on those too???

Torque wrench is NEEDED for critical applications like Heads. Where the bolts have to be tightened evenly AND tightened in a specific order. If you have a cast oil-pan or cast valve-cover then torque wrench is recommended along with the standard "H" pattern.

But this ONE bolt...While it's important to get it right....you DON'T NEED a torque wrench to do so.

thanks for the replies.

like to do things by the book. especially when dealing with a high mileage vehicle that I want to last. I have worked on cars some, but i would definitely not consider myself an experienced mechanic

Of course I found that link about an hour after posting this

I totally agree. Every bolt has a torque spec. The only time I worry with a torque wrench are when doing engine work or lug nuts.

I stopped counting how many cars I've owned at 30 cars and I've worked on all of them. I never said that you NEED to. I just answered the OP's question. I do need to do my plugs soon so I'll make sure to use my torque wrench
