Coil Spring Binding...New Struts and Strut Mount


Recommended Posts

Hello,

 

I'm new to the forum and Edge family and need a quick question answered. I recently replaced my shocks and struts the other day and finally got around to driving it and noticed when the wheel is turned to the left or right the springs sound like they are binding up and makes a loud boiing noise (not sure how to spell that honestly but I think you get the idea). I replaced the shocks and struts with Monroe OESpectrum shocks and struts along with the Monroe strut-mate mount. Everything went smoothly and I reused the bump stop and upper and lower spring cushions. The strut mount didn't come with the upper rubber spring cushion so the old one was used and was in good shape. The only issues I had was getting the strut mount bolts tightened down to the tower without destroying my hands. After about an hour I got it all buttoned up. Come back the next day and see about 3-4 threads exposed on the strut mount and re-tighten the nuts back down (how does this happen?) do struts need to settle? Anyhow when I turn the wheel I can hear the springs bind. Did I perhaps over tighten the strut mount to the tower? Any guidance would be greatly appreciated.

I should also note I didn't back off the 10mm for the springs as Ford calls for. I just found a service manual and see that was required for both the upper and lower spring ends. Also, when installing the mount there was no arrow only an indent on the strut mount. The arrow was installed facing the engine. Ford notes the arrow should be perpendicular to the lower strut mount. These are the only two areas I see issues with when I completed the install. Again, any help would be greatly appreciated!

+1 on the bearing mount. Remove the cowl for better access to the nuts on the mount. Not sure what a strut mate is, but the geometry of the spring and strut should exactly match what you removed. I'd compare the old strut and bearing with the new to make sure all the "spring receiving surfaces" are in the same places.

 

Be careful not to distort the strut tower with an improperly fitted bearing mount. There's a lot of force applied there, from both the mounts and the impact from the strut. Seems to me that it's binding and the spring and strut are not turning as a unit. The boing you hear is probably the spring reseating in the mount or strut.

 

Good luck.

Mac in your video of the 2008 Ford Edge you used Monroe OESpectum shocks so not sure what you mean by not using Monroe parts but either way I'm going to take off the struts again tonight and take another look at it. When it's off the vehicle is there a way to evaluate the strut mount for movement?

Yes and I learned my lesson. The Monroe rear shocks were the only time I used them and they leaked after just 50K miles of use. Been using KYB ever since. I have always used KYB for struts.

good to know Mac. Took them off and put the strut mount in the correct orientation; perpendicular to the bottom of the strut and it turned without issue. Took it to get an alignment and wasn't to far off but still needed some adjustments. All is well now and I'll continue to monitor the quality of the struts and shocks. It's not my daily and my wife uses it once or twice a week to get groceries and get the kid around so I'm not all too concerned considering the price/quality of the product. Your videos are great so keep 'em coming!
