Upgraded Nut Reduces Strut Assembly Noise

Challenge:

Common noise complaints on popular CUV, SUV and passenger car applications

Noise issues related to new replacement ride control units on popular CUV, SUV and passenger car applications can be caused by distorted, threaded lock nuts. The lock nut design as well as manufacturing process is critical to noise-free performance for certain applications, noted in the chart below.

On these vehicles, if the nut is over crimped, it can be difficult to thread on the stem. This results in a gap between the rod and mount where the stem can move, often leading to unwanted noise.

Solution:

Upgraded Nut with Nylon Insert Helps Prevent Noise

Most Monroe® Quick-Strut® assemblies feature a nylon insert to ensure the lock nut is completely threaded on the stem and in complete contact with the mount. This nylon insert provides a more consistent “prevailing” torque (amount of torque needed to run a nut down a thread) and requires less friction when threading the lock nut onto the stem. The result: a completely threaded nut.
