I bought two shock absorbers five months ago. I installed them on my 2015 Ford F150. I have since heard a loud noise from the driver's side suspension. It was a pain in the neck. I've replaced the strut brace, two stabilizer arms and even the wheel bearing assembly. All my work didn't fix the problem. Finally, I took my truck to the mechanic. He diagnosed a bad defective shock absorber. If you have any problem after installing this shock absorber, please return it immediately. Wasted money and time!
