    Leaf Spring Isolator Bushings

    Posted by Sam on 2021 Aug 6th

    My 2015 F150 would make a clunking noise from the rear end over bumps, it absolutely drive me nuts because I couldn’t find the source of the noise. After some research I found the problem was the isolator bushings. The ATQ ones are the absolute best replacement available, the noise immediately went away and I can enjoy driving my truck again, i highly recommend!!

    Solved my noisy rear end issues. When ever I would come in or reverse out of my driveway , it sounded like some thing was loose in the rear of the truck. Checked everything over, and all was good. Get in to leave again, same thing over again. So a quick research over the net prove it to be the isolators that are between the leaf springs. Further research brought me to here. I ordered this product up, and received it quickly. Installed the new pads in, and the loose sounding noises stopped. Was hard to believe with only 18,000 or so kilometers on the truck that the oem pads were really worn, and that’s with no hauling anything around in the bed. Make sure to lube up the pads, and area of the leaf where the pads go like recommended. Don’t need lots but some lube will keep the creaking/ squeaking sound away, and be like new again. Within the first few weeks I experienced those sounds as I didn’t lube those areas up. Poly material need the recommended lube. Don’t install dry.
    Thank you for the great product.
