i have a 2002 buick rend.what would be the average cost for rear spring coil? on 2002 Buick Rendezvous

I took my car in for new rotors the mechanic told me theres a light crack on rear coil spring that he recommended to be fixed. I was hoping to find out here first, because you guys were a big help before with my question . I certainly appreciate any help! spent enough money on the rotor job :{ this 2002 buick rendezvous is costing me. thanks for any info.

You can get aftermarkets for about $80 dollars. Then add labor. http://www.autozone.com/autozone/parts/Duralast-Coil-Spring-Rear/2002-Buick-Rendezvous-2WD/_/N-jg8spZ8oy1q?itemIdentifier=55867_195152_0_

its between 400.00 and 500.00 depending on where you get the springs. aftermarket are cheaper and of course the dealer is more. aftermarket springs are fine so shop prices on the parts
