I had to replaced one of the two bolts securing the rear upper control arm on the passenger side (the previous bolt somehow fell out) with a brand new OEM bolt. I now hear a crap load of noises when I drive over dips/bumps from the same location of the car. When I installed the bolt I just screwed it in. I am posting because I wanted to know if grease or some other lubricant was supposed to be added during the installation process. I looked in the Helms manual but nothing is stated. Can anybody shed some light on this?

 

Might try to preload it and use proper torque.

 

How do I preload it? Jack up the knuckle before/while installing ?

 

anybody?

 

just looked it up in the Honda S2000 service manual--says to preload it, after you lightly tighten the bolts--raise the suspension to load it with the vehicle's weight before you tighten the upper arm bolts---- torque specs are 132N-m or 97.6 lb/ft
no lube or grease is mentioned.

 

Thats what I did. Still makes noises. God damn this.

 

I'm looking at this myself to avoid the dreaded s2k binding. I have a mild antisieze from permatex for brakes (looks identical to the honda pad grease). I plan on lightly dressing the shaft of the bolt, but not getting anything onthe threads for a proper torque reading.

 

Whats that?

 

Preloading, antiseiz and proper torque is always a good thing as mentioned above by others. I use antiseiz on almost everything, it can make a world of difference when removing a bolt. It is important you coat the entire bolt. (including the threads) You might want to check the bushings and other parts tied into the suspension. I had a metallic noise some time ago, I got under the car and found it to be my endlink. Some how it came loose and needed to be snuged up.
