Going to be replacing the lower control arms on my '09 Fit base, and you are supposed to replace the arm mounting bolts when doing so. I referenced the following procedure guide, showing 4 bolts 14 x 1.5 mm
Front Lower Arm Removal/Installation :: Control Arms (includes balljoints) :: Suspension :: Chassis :: Honda Fit 2007-2019 Repair Manual :: Second generation (2007-2019) - HoFit.org
However, when looking them up here, there are several different bolts shown in the diagram

Item # 14, 2 req'd

Item # 15, 2 req'd

Finally, in the diagram a dotted box labeled B-48 there appear to be 2 different size bolts, one of which may be an item # 15 (?). There isn't a part listing for this B-48, so I'm stumped on this one. Who has done this job on a 09 Fit, and what are the actual sizes and their respective P/N's

Bolt sizes needed for arm replacement?

 

I swapped mine out a couple of years back and vaguely remember the same confusion around the bolts. Try checking a separate diagram for the front subframe and I think you'll find the part listings for the bolts in question.

My educated guess is this:

B-48 is the front subframe diagram - TK64B4800.



If you peep that diagram,your mystery bolts seem to be 5 (90162-TF0-000) and 7(90165-TF0-000)

Thanks Julian! Good eye on that, tough to tell between diagrams! So #4, 5 & 7 for the triangle subframe attach point. And #14 here for the LCA forward hinge point

Confusing to have to jump between 2 diagrams. Big problem if you screw up and order the wrong bolts with stuff laying disassembled. Why don't they just sell a kit pack for LCA replacement?

 

FWIW, I re used my bolts when I swapped my LCA's. it would be a smart idea to have a spare set on hand, in case one were to somehow have non-reusable bolts.
