Torque spec for control arm

[sullivas]

Hi,

 

I was looking for my front end noise problem and I discovered the bolt that attaches the

lower control arm (wishbone) and holds a horizontal bushing to the crossmember is loose.

It is 12M x 1.5. About 4" long.  

Given the attached chart should I use 89ft lb or 56ft lb torque?  Also, the face of the nut is kind of shiny from friction,

I don't know if it was a ribbed type for locking purposes, I don't see any evidence that it was.  The inside

of the bolt cap is somewhat smooth as well..  Should I replace them with new?

I hope the looseness of the bolt hasn't rounded out the attachment ears. 

Thanks in advance.

If it is the bolt where the control arm attaches to the cross member, it is 89 ft. lb.; 56 ft. lb. is for the wheel carrier end of the arm.

 

Without seeing the fastener, it is impossible to say if it needs replacing.
