Installing RCA's... need torque specs!!!
Hey all,
I am installing my RCA's today and I have been told by Exact to torque the two bolts that connect the lower ball joints to the steering knuckle to 120 ft-lbs!!!! I thought that was high so I called my Lexus dealer and a guy there told me 83 ft-lbs...? So I am not sure what to torque them to? Anyone have these installed?
Or does anyone have a manual so that I can verify the torque specs?
My bucket is a 98 GS400!!
Thanks,
Marcus

Ugh..I hate those hex bolt. Very inconvenient to torque unless you have the hex adapter. I prefer a regular flanged bolt myself (same as OEM, but longer).
If exact says to torque it to 120, then I guess you should torque it to that spec. I dont know how they came up with the number. Perhaps you can PM RMMGS4. He's running the same RCAs.

So longer and stronger than OEM is what they were shooting for.
The background on these RCAs was there were 5+ of us using these in NorCal on a Long Term basis to test, before Exact offered these to the public.
No problems from the original 5 users and nothing I've heard from the many other locals that have installed them since.
I believe Jawnthen has the most mileage on these RCAs. His car is at 170k right now, but I'll have to ask him what his mileage was when he installed them.

If I recall correctly, I think Exact told me that they're using Grade 12 bolts as opposed to the standard Grade 8 bolts.

Got a little off topic here guys... So RMMGS4... what torque specs did you torque yours down to regardless of how strong the bolts are?
