Leading evidence: 'Install roll bar and now it squeaks' (no explicit attributable resolution; this is a reported action or suggestion). Across 1 matching discussions, The most frequently discussed action is 'Check any binding' (1 discussions). For that action, 0 discussions report a resolution and 0 report an unsuccessful attempt. No action has an explicit, attributable resolution report under the current rules. These are forum reports and suggestions, not a confirmed diagnosis.

You may want to spray some lubricant in the area first to see if it changes anything.

Maybe loosen and remove steering rack bushing one at a time and lube it with heavy duty marine lube(or the same stuff they use on swaybar bushings).

The major complaint when using polyurethane bushings is squeak.
Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

I swear, this car is gonna drive me to the asylum. One step forward then two back. Ok, 99 has the coveted ROW 30 suspension. Love it and it's been flawless. I installed a tecquipment roll bar recently and now the suspension is squeaking when turning. WTF? Totally new symptom. What has this roll bar done to my car? Too stiff?
This is more of a rant than a help me post since the answer is probably going to force me to donate plasma and sperm for parts cash.
Are you sure the squeak is coming from the suspension? Could be steering etc. Can the noise be reproduced while at a standstill? Easier to diagnosis if so.
I would first check for any binding with the end links. Did you use stock end links? You could always take the bars off and see if that fixes the squeaking. They are pretty quick and easy to swap without throwing parts at it.
First rule of mechanics - always go back to the last thing you did. You installed the roll bar and now it squeaks. Remove the roll bar completely and see if the squeak goes away. If so, put some silicone grease on the roll bar attachment points and bushings when you put it back on. If the squeak is still there with the roll bar removed, then some other part of the suspension or steering rack needs to be checked.
It could be that the roll bar tightened up the chassis ever so slightly where your bushings for the steering rack bracket is binding just enough to squeak. IIRC, you have a '99 C2 which has slightly less stiff frame, especially in the front tub area than the c4 and mk2 models. Maybe loosen and remove steering rack bushing one at a time and lube it with heavy duty marine lube(or the same stuff they use on swaybar bushings).
Resurrecting my own thread. I haven't had time to dig into the squeak. Alps, are the bushings you mention easy to get to? I will see if I can find a diagram.
Well, just came in from the garage. Everything got a nice lubing (the suspension, you freaks). On jack stands, the noise is gone. On the ground it sounds like an old farm truck. After the lube session the horrendous squeaking is still there. It squeaks over bumps and when turning wheel.
Since the symptoms didn't appear until after the roll bar install, it is coming out this weekend.
Why not just loosen the bolts first and see what happens? If it only happens when the bolts are really tight, you maybe able to get away with using some spacers to shim the rollbar out from the chassis.
