Well I have a steering clunk, I think it's from the springs rubbing on each other. Going to get these:
Silence Noisy Coils
Use Whiteline's new spiral coil wrap to silence noisy progressive coil springs. Most new cars use coil spring insulators to reduce NVH resulting from coil bind or contact between "dead" or closed coils. Many aftermarket springs require a progressive design using "dead" coils to meet captive height design requirements. These can become noisy under certain loads making an add-on insulator very useful.
The spiral design lets you insulate the springs WHILE the coils are in the vehicle saving time and money. Each pack contains 1.5 metres of heavy duty plastic spiral wrap which is enough to do 2 springs.
There are two options:
Whiteline K60950 10-13mm Black Coil Spring Silencers . . . . . $9.00/package
Whiteline K60951 13-18mm Yellow Coil Spring Silencers . . . . . $12.00/package
Do I get the 10-13 mm or the 13-18 mm ones?
