Exhaust rear section removal

Just wanted to get a general consensus here on what most people are doing when removing the rear section. The two front diff bolts where the hangers sit, the manual calls for 100NM to secure the two bolts. My torque wrench unfortunately only goes up to 60 ft lbs.

How many of you are A) just tightening as much as possible or B) using the correct torque specs? Thanks

You do not need to torque any exhaust bolts except for the manifold bolts since they go into the head. Just snug them up. Don't overdue it. I find most people that are not mechanics overtightened things. Nice and snug is plenty tight.

just get them tight and forget about it.

according to this post

the bolt in question is only 26ft/lbs. I think people used to overtightened this bolt resulting in broken diff bolt. if I'm not mistaken, diff bolt screws into the diff itself and thus the exhaust hanger bolt doesn't need to be tightened so high.

I'm confused now. #6 is what I'm referring to but that bolt also holds the front diffs which has a torque spec of 100NM I'm referring to. The two front diffs bolt onto the subframe and comes out of #6.


Differential Drain Plug - 60 NM (44 ft lb) - 14mm Hex
Differential Bushings (front) - 100 NM (74 ft lb) - 18mm socket
Differential Bushing (rear) - 165 NM (122 ft lb) - 21mm socket

right. diff bolt is threaded into the diff. it'll not come off when you undo the exhaust hanger nut.

Thx. That's what I figured but was unsure.
