Torque bolts front sub frame

[JensVdb]

Hi everyone,

Busy reassembling the front sub frame, but I'm not sure how hard I have to tighten all the screws.
I rather play safe and ask than do my thing and have damaged parts after.

Anyone who can help me out here?

Thanks in advance!

Very nice, very very nice! When I assembled my sub-frame components I used the scientific measurement of "very tight".. without stripping. I used an electric 3/8" drive impact to do the ball joints- but be careful, you can feel when they're tight and then the pins will hold them, not sure if there are torque numbers for those components, but even with that there are a few swivel joints that will spin if not put on with some kind of impact. I check mine whenever I'm under the car but after 5K miles nothing has loosened up.

Good luck!

You should always refer to the blue book for torque settings; but this is a very good guide based on the bolt size and the grade.

^^ what he said. It's all (most of it anyway) in the blue books. Nomenclature can be confusing at times. And don't tighten #5 until the car is on the ground, loaded as specified in the book.
