Clunking Noise Over Bumps
We feel that there’s nothing better than a nice smooth riding vehicle. Today we met a new customer that feels the exact same way but was going crazy because his vehicle was making a Clunking Noise Over Bumps. Rattles and clunks can almost feel like a form of torture to someone that’s sensitive to them. Not to mention that in most cases a noise can mean that there is a component in the suspension that is loose and could pose a safety concern for the driver.
Suspension Clunk
The first step in any diagnosis is verifying the problem. With this vehicle the customer was a little bit frustrated because he had been going to another local shop that replaced a few suspension parts in an attempt to remedy the issue but unfortunately never got to the root of the noise. When the vehicle came in we took a ride with the customer. The goal is to hear the same noise he is hearing so that we’re not chasing a “normal” noise or another noise he’s not concerned with.
After a short ride together is was very obvious that the noise was coming from the front suspension. Next we had one of our Technicians inspect the vehicle on a lift. We found that the suspension was tight and everything looked normal so we had to go a step further. We opted to use chassis ears on this vehicle. Chassis ears are like little microphones that
the Technician can hook up to various spots in the suspension and listen to certain areas to isolate the noise while driving on the road (it sounds complicated but it’s really not).
Strut Noise
After a short road test the Technician found that the noise was coming from the front struts. The struts on this vehicle are filled with an oil that helps dampen vibration in the road. While the struts appeared to be in good shape and full of oil, they had developed a bit of play internally causing the clunk. To fix his concern we needed to replace both front struts.
Strut Replacement
We removed the old struts and replaced them with new ones including new strut mounts and strut bearings. The reason we do this is that the mounts are a solid rubber and compress over time
and the bearings take quite a bit of abuse over the years from turning and hitting large bumps. Since they have to be removed from the old strut anyways, it’s best to put new ones on the new strut to ensure
the best possible end result that will last for years to come without any issues. There would be nothing worse than putting the whole job back together only to find that there is still a small noise from the mounts or bearing.
In this and every case the customer is given options. We ended up replacing everything because that’s what the customer wanted. The additional expense was only about $100 and the customer was able to take advantage of one of our Payment Plans so he could defer payment for a few months. We also backed the repair with our 2 year 24,000 mile nationwide Warranty and 12 months of roadside assistance.
The end result was a smooth running vehicle without any rattles and one very happy new customer. If you have a noise that’s bothering you it may not necessarily be a safety concern, but it’s always better to be safe than sorry. Noises like this can also cause some uneven tire wear that will result in a second noise. Feel free to give us a call today or schedule online. We’re happy to help.
This noise was driving me nuts to the point of wanting to get rid of the vehicle. I was thinking there was something wrong with the frame or something major. David was great! He set me up with one of the guys over there and they had me in and out in a day. I think the price was very reasonable and frankly the car has never driven better. I’m happy I gave them a shot and will be back for all services whether minor or major.
