Have you ever travelled on rough terrain and when you hit the bumps even at a slow speed, you feel like there is an earthquake? Yet, you could swear it wasn’t always like that when the car was new. You can probably tell there is an underlying problem
That is the time when you know you need to do a thorough check-up on your suspension system since it is designed to absorb vibrations and other impact forces when you hit the road. Here is how:
Do a thorough inspection of the suspension system
The suspension system needs to be inspected after a certain amount of kilometres depending on your car. Alternatively, you can inspect it every time you schedule an oil change or replace your tires.
Remember, the suspension system is very broad and it doesn’t just include the shock absorbers and struts but also the linkages, steering system, springs, bearings, and tires.
1.Inspect the rubber bushings
The bushings are usually cushioned with rubber to absorb vibrations and regulate movement between the suspension parts. Unfortunately, the rubber can get exhausted after a long period of time thus affecting the overall performance. If it happens, the most prone areas you should inspect are the struts rods, track bars, sway bars and control rods.
2. Watch out for visible signs of cracks, swelling and oil contamination
Okay, checking the suspension parts for signs of swelling, contamination or cracks can be challenging for a beginner. If it isn’t your forte, you can schedule an appointment with a mechanic or a professional service here https://www.pupkewitz-motors.com/service-parts/booking/
However, if you don’t mind doing it yourself, you have to go under your car to give a closer look at the shock absorbers and springs. Don’t forget the hydraulic system, linkages, bearings, joints, and wheels. Basically, all the parts that make up the suspension system.
3.Get rid of debris or oil contamination on rubber bushing
The rubber bushing doesn’t need oil for lubrication. In fact, oil is the most frequent trigger of rubbing bushing failure followed closely by debris and age causes. Usually, when the rubber bushing is exposed to oil it becomes too soft to do its job, while the debris prompts wear and tear. You can clean the oil and debris off the rubber bushing using a degreaser.
4.Check the ball joints
There are two methods of checking the ball joints. The first method is easy and you don’t have to get your hands dirty; just hit the road and if you hear any banging sounds when driving or feel the steering wheel stray or vibrating too much, then you’ve likely got a suspension ball joints problem.
The second method involves jacking up the car, removing the wheels and closely examining the ball joints. When inspecting the ball joints, you have to watch out for signs of grease leakage, rust, damaged rubber boots or anything that indicates you need a replacement. Moreover, you can check if the ball joints are loose by using a pry bar.
5.Re-fill the grease fittings
Compared to cars, most trucks come with grease fittings on the suspension system. The fittings should be topped up with grease after every oil change schedule to avoid any future complications. It can be done during a professional service check or you can do it yourself using a grease gun.
6.Inspect the struts and shocks for oil leakage
To check for signs of oil leakage on struts or shocks, you have to uplift your car using a jack stand for a better angle. Since they’re part of a hydraulic system, you should schedule a replacement if you see any oil leakage or confirm that it is wet.
7.Perform a bounce test
If you want to verify if the struts or shock absorbers are in good condition, you should perform a bounce test. How? Simple, just put pressure at the seam or car corner and push it down to create some type of bouncing motion. If the car bounces more than two times, it is an indication that the struts or shocks ought to be changed.
