Why does my shock squelch?
Squelchy noises. As a rule, your shock should be pretty much silent in operation. If it starts making more noise than usual, it’s definitely unwell. A squelchy noise on compression and rebound is usually a sign that the seal that separates the damping oil from the pressurised nitrogen charge has failed.
What is a trunnion shock?
WHAT IS A TRUNNION MOUNT? A Trunnion mount shock mounts the shock body directly to the linkage – there are two threaded holes on the shock body and linkage bolts thread directly into them. Trunnion mounts have started to become more popular within the last few years with frame manufacturers.
How do you know if your rear shocks are blown on a mountain bike?
Quote from video: Number one would be if you lose early dump it in and you will probably end up with some oil somewhere. Whether it's coming out with your dresses. Or on your shaft.
Why my rear MTB shock is making a whooshing noise?
Just had mine push tuned, in the information they send back with the shock they state the whooshing is normal as the air/oil move through the channels within the shock. It’s quite apparent when you bounce on the bike (bunny hop etc).
Do rear shocks leak oil?
Shock absorbers are small oil pumps with a piston inside. They’re filled with oil and usually have a rod that goes through the top of the shock. The top of the shock has a seal that stops any leakage, but this can get damaged, and the oil leaks out over time.
How do you know if your rear shocks are blown?
Testing Your Shocks: How to Know When “It’s That Time”
In a clear parking lot, start with the car at rest. Accelerate hard and then brake hard. If the rear end keeps bouncing, your rear shocks may be worn.
Should I grease shock bolts?
Bolts do not need grease. You can use it if you’re worried about corrosion as mentioned above. Loctite isn’t usually needed either, nylock nuts are a much better option.
How does a trunnion work?
Trunnions are precision ground bearing mounts that allow you to mount a fixture to the surface, usually on a riser, and will allow full rotation of the fixture and parts placed on it.
What is a DU bushing?
DU® self-lubricating split bushings offer very good wear and low friction performance over a wide range of loads, speeds and temperatures in dry running conditions. Bushing material suitable for lubricated applications. Anti-friction bearing suitable for linear, oscillating and rotating movements.

How do you clean rear shocks?
Clean the stanchions of the fork and rear shock using the micro-fiber towel. Be careful not to push any debris into the dust wiper. If there is heavy dirt and grime, we suggest using isopropyl alcohol first, by spraying the alcohol onto the stanchions and wiping them clean with the micro-fiber towel.
How do I know if my bike shocks are bad?
You may notice that your motorcycle starts to swerve when you applying the brakes. Worn shock absorbers could cause your bike to swerve as well as making an unusual knocking sound in the process. If you notice any unfamiliar movements or sounds, then it could be time to get your shock absorbers replaced.
How long should shock absorbers last?
Shock absorbers life expectancy, as well as the struts, is at least 4 to 5 years. Nevertheless, it actually depends on the road conditions. The lifespan can extend to even 10 years if you drive the car mostly on smooth pavement.
How often should shock absorbers be replaced?
every 50,000-100,000 miles
Generally, shocks and struts wear out every 50,000-100,000 miles. If you’re a more aggressive driver and/or frequently drive on rough roads, they will wear out faster. Shocks and struts don’t go out all at once; they deteriorate slowly over time.
Do shock absorbers have oil in them?

Is it normal for new shocks to make noise?
There is most likely nothing wrong with the replacement shock or strut, but a metallic clunking noise typically indicates loose or worn mounting hardware. A loose mount can allow movement between the bolt and attaching parts, while a mount that is worn can cause the shock/strut to move up and down.
Do shocks make noise?
Worn Shock Absorbers
A shock absorber is a damper that is designed to absorb impulses from the wheels. Shock absorbers make driving in rough terrain bearable, but they are also prone to damage. If they break, you will hear some tapping noise, especially if the bushing is cracked.
Why do my rear shocks squeak?
In addition to the shocks and struts, the squeaking also can be caused by worn ball joints or bushings. Your ride quality is poor. If you are starting to feel that your vehicle is more bouncy or rough or tends to “roll” on turns, it’s time to get your vehicle’s suspension inspected.
Will WD40 stop squeaky suspension?
Because WD40 is a water-displacement product, it will dry out the problem area and create a more significant issue. This product may temporarily stop the squeaking because it adds instant lubrication, but WD40 will displace moisture as it evaporates, creating a more substantial problem.
Can you lubricate shocks?
Lubricating the upper isolator, jounce bumper and utilising the correct internal strut/shock oil will help reduce friction, noise, vibration, and harshness (NVH) in the suspension.
