I was changing my oil today and noticed that my rear leaf springs had a wavy look to them. They curved down like usual but then curved up where they went over the axle and then looked normal after the axle. Is this normal? I know a picture would help but it was dark outside. I will try to post one tomorrow.

It is normal.

I think its normal, i have an 03 QC and the springs are the same way.

ya ive always wondered why they are like that..... ud think they would be as strong as a regular leaf spring with an arc in it
