tried with this wrench we sell at work BUT still couldnt get the locking nut off.

Hey Brian, do you recall how you eventually got that lock nut off? I tried doing this yesterday because of loose steering I have but that damn nut is next to impossible to loosen. Going in I knew that it would have been tight so I sprayed some PB Blaster and let it soak in for at least 35 minutes while I did other things. I used a tool similar to what you have posted but it didn't work. Probably not having enough leverage didn't help either.

Ha! Here in the south west it's a piece of cake. No rust on my car.
The way to tighten it is to go till its tight then back it off a little. Drive to make sure your steering wheel returns to center if not back it off a little more till it returns to center but no more. Also if your nut is an outy you need to get the update.

Just found this thread wondering if it would fix my issue. I have this intermittent problem where the wheel will shake when going over 60mph, and it feels like a shake through the steering assembly itself(aka not an unbalanced tire). Also, i feel(more so than I hear) a clunk through the steering when I go over sharp bumps or pot holes, it feels like something is bad or loose.

I took it to an honest shop who inspected it and took it out for a test drive even and could not find any issues.

Could tightening this fix my problem? Or does something else need to be tightened?

It is my personal opinion that tampering with the steering rack specs is not a very good idea , at all .
Most of the vibration problems are usually bushings , lower arms and the wheels . These aftermarket wheels are somehow difficult to balance to perfection , and the so called "high speed balance machines " are a joke . The mechanic would hook the tire to the machine , spin it for a very few seconds (maybe 20 miles per hour spin or so) then stop it and that is how they balance the tires ... the tire being balanced is not made to spin at higher velocities where it can be really completely balanced .
That is how you get slight vibrations at 40 mph and more intense after 60 if there are some other problems like bushings , wear tires , etc .

I had the same issue. They checked the steering rack, tie rods. All the normal culprits...and nothing. So, yesterday I tried tightening the steering pretensioner. The vibration is still there but very little. I think this made a pretty decent improvement and didn't cost anything. Totally worth it to me. Good luck.
