I replaced the rack on my R20 about 18 months ago and at the time I put in new rack to steering arm rods. I "locktited" or should that be "loctightened" them and did them up with the new special lock washers. Well whilst holidaying the passenger side rod fell out. On examining the rod it had come loose and the hardened rack had chewed out the thread on the rod enableing it to come completely out. Very scarey.
What have I done wrong?
