To lubricate the shocks and struts, jack up your automotive and take away the wheel for entry. Take your lubricant and spray it on the bearings, flip plate, and bushings.

After it’s correctly set, replenish a grease injector with grease. Apply it to the identical components. Repeat this course of for each shock or strut.

That was only a glimpse of methods to lubricate shocks and struts however there’s rather more to be mentioned. So, keep on with us until the top.

Lubricating Shocks and Struts: Step-by-Step Information!!

If the shocks or struts begin to squeak, you’ll must lubricate them. Since shocks and struts are completely different elements, their lubrication course of is completely different.

Steps to Comply with earlier than Lubrication

However, earlier than you begin lubricating, there’re some issues to contemplate. So, be certain that to:

  • First, jack up the automotive and take away the wheels to realize entry to the suspension system.

Step 3: Spray Lubricant

Now, take your lubricant and fix the lengthy nozzle to it. Then, spray on the strut bearings, flip plate, and bushings. You’ll have to carry down the mud cowl whereas spraying the bearings. Wait a couple of minutes and spray once more a number of instances.


Step 4: Apply Grease

Take the grease injector and fill it with grease. Now, inject the grease into the flip plate, strut bearings, and bushing. Make it possible for the grease doesn’t leak out from across the injector nozzle.

Once more, use an extended nozzle for any areas you possibly can’t attain with a standard nozzle. Repeat the identical course of for each wheel.

With that, your struts have been lubricated.

Shock Lubrication

Now, how do lubricate shocks within the automotive? To lubricate the shocks, you possibly can observe the struts’ lubricating course of as they’re nearly the identical.

The one distinction you would possibly face is the mud cowl. Struts have mud covers on them which must be held down for lubrication. However, shocks don’t have this cowl.

Additionally,  it’s finest to make use of shock absorber oils like Waxpol to lubricate shocks.

When to Change Shocks and Struts?

It’s best to change the shocks and struts of your automotive after each 50,000-100,000 miles on common. Relying in your driving, it might last more or shorter.

However you possibly can look out for these signs that point out your automotive’s shock or struts wants substitute:

  • Once they’re worn out, it’ll be exhausting to regulate the automobile.
  • Fluids will leak from the outside of the shocks and struts.
  • The tire treads will even be uneven.

Shock Alternative

Simply take away the bolts of the shock and it’ll come out. Then, put within the new one and bolt them sustaining the beneficial torque. Make sure you match the shock together with your automobile’s particular mannequin.

Normally, you don’t must take away the shocks for making use of WD40. However, if there are critical lubrication issues, disassemble first. Additionally, keep away from utilizing extreme WD40.

Are Shocks Stuffed with Oil?

Sure, shocks are stuffed with hydraulic oil. They’re connected to a piston. Throughout the bouncing actions, this piston strikes throughout the hydraulic fluid. Thus, the stress is tremendously absorbed by the oil which reduces the influence. At all times ensure that the shock is 90% stuffed with oil.

Can I exploit Engine Oil as Shock Oil?

No, engine oil shouldn’t be used as shock oil. That’s as a result of it reacts to the temperature. In hotter temperatures, the engine oil will get thinner. Whereas, in colder temperatures, the oil will get thicker. This can change the dampening issue. Thus, it’s finest to make use of silicon oils which stay fixed.

Backside line!

Hope you bought to know every thing about methods to lubricate shocks and struts. Nonetheless, right here’s one final tip. When altering your worn-out tires, change the shocks as properly. Thanks for staying with us until the top.
