I just re-insured the X and drove to Kal Tire for a wheel alignment after finally finishing the installment of the LCAs, WBHAs, outer tie-rod ends, sway bar bushings and links. Is there anything special I should do? Additives for the gasoline tank? Sea foam? I sea foamed the WD-21 pathfinder a long time ago and ended up destroying a cat. That might have been my fault for using too high of a concentration in the gas tank. Everything seems to work just fine on the X. The ABS and other lights that came on from the worn out wheel bearing and hub assembly (WBHA) went away as soon after I started driving. No SES, no codes. Suggestions? Thoughts? Do nothing other than fill up the tank? Incidentally, I changed the oil after it sat in the engine for well over 2 years. The Mobil 1 Extended Performance 5W 30 oil looked great. It was still translucent. Figured it was time for a change.
