2013 Suburban Rack & Pinion

[KevOLTZ]

Do we know if the rack is adjustable / greasable? I just did the bushings and noticed there is a lock nut and a plug just like on the Lexus trucks. Didn’t know if you pulled that plug out it’s either adjustable and or greasable, and would tighten the steering up?

It is not adjustable, there is a spring and some other parts under that cap that keeps tension on the rack.
