I haven't used ramps for probably 20+ years. I have never cared for them. Maybe I just don't understand how best to use them, so here are some genuine questions for all the ramp fans. These are based upon my experience with ramps.
1) Many of my cars have had a very low approach, and the car scrapes on ramps before the tire ever reaches the ramp. What do you do? Longer ramp approach?
2) Question 1 leads to this next question? Doesn't the ramp portion get in the way when working on certain projects, like transmission fluid changes? How do you deal with this inconvenience? And wouldn't a ramp with a long approach be even more in the way?
3) To do many jobs right, a car needs to be level. Transmission fluid drain & fill, for one. Rear diff drain & fill for another. How do you level a car with ramps?
4) And question 3 leads into this last question. How do you do work on the rear end of the car, such as rear diff fluid change?
