D2 owners! Need help! How big are the springs?

[publicenemy137]

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?

why don't you email them and ask what's the difference between the two ?

[ma71supraturbo]

I'll check for you on monday :)

[publicenemy137]

thanks supraturbo. And s13driver, b/c that's at PDM racing, not D2's site. D2 people speak only taiwanese, so I wouldn't be able to ask them.

wow, this looks like a neat item which just may be crazy enough to work. Interested to see which ones to get. (Black would be great since the coils are black!!)

[publicenemy137]

yeah it does look pretty neat and interesting. I'm also looking into other silencers but not coming across any yet. I heard Tein has some but didn't find any on their website

before you assume its your coilovers (like I did with my d2's) take a look at your tie rods. Mine were so shot it was ridiculous. I replaced them with tein tie rods and all the noise went away. Also,check your steering rack bushings- Rob

[sr240mike]

As well as tension rod bushings. Also try greasing the upper mounts, it helped on mine(D2), What spring rates do you have?

[publicenemy137]

7/5. I'll try greasing the upper mounts. The t/c rod bushings are fine

did yours just make noise when driving or only when you were turning the steering wheel?

I already replaced my tie rods with Tein Tie rods as well. steering rack bushings and all other bushings are fine. Can tell the noise is coming from the springs

[sr240mike]

I got this directly from that page, this is what it says about the top insulator.
"Does your front end pop, clunk and make grinding noises when you turn the wheels. When you are backing up out of your driveway, do you hear a violent metallic “POP” noise? Replaced your TC Rod bushings and still hear a clunk up front? Chances are, your top spring perch bearings are gone, and you are hearing the clunk of the bearing or the spring actually releasing as it winds itself up due to the bearing not allowing the spring and suspension to rotate through the 240SX’s proper swing. Dirt, grit, water all attack this actual bearing inside the mount and we see this situation time and time again on cars that come through our shop. Solution, change the entire unit today with an OEM top spring bearing mount insulator. This unit is a bearing mounted inside of metal cup that is surrounded by rubber to help isolate road noise, vibration and allow deflection of the spring assembly as your car’s suspension is turned and twisted. Over time, the bearing is attacked by water, grime and dirt, and the rubber breaks down from heat, salt and freezing. If the bearing seizes, it will not allow the shock assembly to rotate smoothly, and binds the spring "

Now obviously you can't use them since you have camber plates, but greasing/cleaning them might help.

D2 says they are 1/4" which would be ~ 7mm

[publicenemy137]

damn. so that means it's too small for both options huh. Anyone know where I can get a 7 mm coil silencer? I've looked around, only found the ones above. I heard Tein sells some but I couldn't find em.

[sr240mike]

1/4" no way!!!!!!!!!!!! Thats way too small. I'll go get my calipers out right now. K, fronts are 11mm.

[publicenemy137]

thanks sr240mike, ordering the coil silencers now

[ma71supraturbo]

Sweet, thanks mike. And let us know how they work Publicenemy -- Im curious

[publicenemy137]

will do. Ordered a set from PDM last night. Not sure how long they will take to ship since it's from Jaahhhhpan! I'm also goin to take mike's advice and grease up the upper mounts this thursday, to see if that takes away from the steering grind
