Replacing the rubber cab mounts on the cruiser and can't find a torque setting for the nuts. Seeing how the rubber bushings need to be squished just enough, but not too much, I want to get them to spec. Can't find the info in my FSM. Done some searching but no luck. Specifically, these are the same nuts and bolts that a person must mess with when doing a body lift. I am not doing a body lift, just replacing the factory rubber bushing$$$$$. I admit my brain is set in it's ways, and I most likely am not coming up with the correct words to search.

Thanks for any help.
 
I have five 80 series manuals, and it's not in any of them. I seem to remember it's in the 60 series body and chassis manuals. I'll look when I get home this evening. If I can find it in them, I'll post the specs.

If all else fails, I would guess that a reasonable torque would be whatever just deforms the bushing, beyond what the body load did, that is.
 
No joy. Looked through another 3 manuals, including the 1984 heavy duty chassis and body manual; no info on those joints. There is a supplement, for every year, that describes standard torque values for fasteners which do not have application specific values. I wouldn't use them, though. I'd rather just put a smidge (that's a technical term) more preload on the bushing, beyond the body load, and call it good. Unlike airbags, you're not trying to deform the bushings, the body load has already done that. All you need to do is to ensure that the bushing doesn't move around which would tend to damage to load faces. The additional bolt torque "squish" will ensure that this doesn't happen, when the body load is released, as is the case when the suspension travel is used and before the body comes back down on the chassis.

HTH
 
Sounds like you'll have to go with the "tight enough" approach and measure with a torque wrench. Then at least the rest of them will be consistent.
 
I looked in my 1994 service manual, and as other members have said no torque spec's listed for those bushings. So i got out my factory Toyota collision repair manual for 1995 land cruiser's. I though maybe those torque spec's might been in there seeing as a body shop might have to R&R the cab, sorry to say, no torque spec's listed. You might want to PM CDan, or Beno, and ask them, if anyone would know they would.

Where did you source the body bushings from? I thought some were not being made anymore.

Thanks.

It's nice to know somethings are still available.

80 series body mounts and some hardware. The only mounts discontinued are the two at the very far back of the frame-to-body interface:

52241-60030 and 52242-60020

All the rest are still available. :)
