Re: [ASC McLaren ] NOW - - I NEED HELP !!!
Well, sad to tell you guys that I am about as "mechanical" and/or "skilled" as your grandmother! I can change a taillamps bulb and that's about it! I do NO work on my own cars and pay dearly to have what needs top be done >>> DONE ! Therefore, I am at the hands of my dealer, who charges $86.25 @ hr. labor rate, just like the washing machine/dryer repairman does. I think I'll wait until late July, and see if the weather (HOT) changes anything, and drive it a bit. If no improvement, I'll have the thing lubed & done in August, requesting to have the steering column sleeve removed, maybe should also remove the leather wrapped steering wheel too, just to be safe ??? The car also had severe "flat" spots on the 4 tires and felt like they were square tires. However, in the 16 mile trip, that went away. They are the original, no longer available B.F. Goodrich Comp T/A P225x50/15" rubber.
