I've searched and can't find.

Anyone know the torque specs for subframe bolts? (For the '98, if it'* different year-to-year)

It'* in my service manual, at least for my '93.. I know this because I looked it up when I reinstalled mine. I can have an anwer for you tonight, once I get home. I can tell you now that it isn't all that much.. So don't go twisting on them with a big ol' pipe on your breaker bar... They tend to come out a LOT harder than they go back in, of course..
I'm thinking like 70 ft-lbs., but don't hold me to that..

I don't have time to check, but I assume you checked Techinfo? I don't remember if I put those in there or not.

I didn't find it in Techinfo.

I'll check my '97 FSM, tonight, as well and if I find it, I'll post it so we can see if there are any differences between the years.

87-99 will be the same for all H bodies.

I assume these are the bolts that go through the insulators? If so, the FSM indicates the spec is 66 lb. ft. Interesting is that it also identifies a "sequence" for tightening, if the entire subframe is dropped:

a. Left hand poistion 2
b. Right hand position 2
c. Left hand position 1
d. Left hand position 3
e. Remaining bolts (sequence optional)

Yet, there is no diagram to show the positions, only a color of insulator and part number assigned to a position :?

If you are referring to the bolts that hold the two subframe pieces together, then the spec is 43 lb. ft.

Position 1 refers to the two front ones and “Position 3” refers to the two rear ones - IIRC.

Thanks for the info guys.

When I get under it to take a look this weekend, I may have more questions as to which position is No 1 , 2 and 3 :?

I am going to do some more investigation on this postion stuff to see if I can determine what is going on. The FSM for '97 is quite difficult to decipher for some things, since it was a year that they changed the layout of teh FSMs. Travis (sonoma_zr2) also has some information that might be helpful that he posted in the "General" section.
