I have noticed a bit a oddness in the steering while on the highway. there is the typical 1-2" dead spot in the center and left lane changes are smooth as can be...right changes are a bit quick and uneasy. I really think I need to go ahead and get the alignment redone after that shop did it wrong. I did adjust the sector shaft a bit and it got a little better as far as looseness, but the rest is still there. maybe just worn...maybe still needs the input adjusted some...not going to mess with it til I get another alignment done though. Miles per gallon? wont matter in the end...but its nice to know what to expect. Mostly i want to know how accurate the gauge is at certain points so I know when I'm on the verge running out of gas. It sat on empty for the longest time and never ran out.
