Hello all!
I had replaced the rear struts (KYB) on my '99 Corolla last August due to car bottoming out on road bumps and shallow roads. I called back the shop and said would check it out if parts are defective and would only charge me $220.00 for labor. Parts still in warranty. I'm hesitant because I have searched and found that problem could be in the springs. It would burn a big hole in my wallet if the springs needs replacement instead because I would pay again for the parts and labor. Appreciate any help or advise please! Thanks in advance! ~Dave.

P.S. Just went to the shop today and found out the front struts badly need replacements. Owner claims this is the reason for bottoming out. Suggested to replace both the front and rear to correct the problem. Please, I'd appreciate any comments from anyone. Thank you so much for your help!
