Fox 2.0 Coilovers failure

Ive had these on truck for maybe 4 years, they have seem some minor action but nothing crazy.

The coil springs yet go the other day and local shops have no clue how to fix them.

Inspection is coming up and I gotta get heaver springs on them as I think the added weight of my bumper + winch adds alot of weight up front.

Any ideas where and what spring to upgrade with ?

Is the swap easy ?

 

Spring broke

 

Both sides same problem

 

$1200 of rusty mess !

Wtf

 

Take them off the truck, loosen the adjuster collar until its at the top of the threads (be careful if your shocks are too rusted), have a shop (or rent a spring compressor from auto zone yourself), and take the spring off. Then replace it with a new eibach spring.

Not too hard of a job.

Edit: DEFINITELY a rust problem, you'll go through hell trying to adjust the collar and probably chew up the threads, good luck!

But to answer your question, the springs are replaceable, fairly simply when not rusted. If you're going to try, id attempt to get as much surface rust off the threads as possible before you go at it.

 

@Boston10Taco Look familiar?

 

lol yea, your shocks are fine, you just need new springs. maybe pick a different brand spring that can hold up to what ever the hell they put on your roads to cause that much rust lol

 

Eibachs have lifetime warranty. They will replace it. I broke a 650lb. Went too 700s they are much thicker.

Are you running any skids and a winch? Were those 650s?

Edit: doesn't look like you have skids, so 700s might be a bit too stiff if you aren't going to add more weight

 

Have you done any service to those shocks in the past 4 years? You’re obviously in a very corrosive environment.

 

Holy rust!!!

 

Thanks for the help guys !

Only service ive done is wash them sometimes beleive it or not.

What service needs done ?

guess I will need that special spanner for the job ?

Any other parts recommend while they are off and being serviced ?

 

Yes, the manufacturer recommendeds a service 15-20k miles, and that’s with moderate diriving conditions. More miles have been reported but that’s the recommendation.

You will not need to adjust the preload collar with the proper spring compressor. I would probably not recommend that route with the amount of rust you have.

Maybe a new coating? You’ll probably have some parts that need replacement with the amount of rust but it needs to be done to have them work properly.

 

Good quality spring steel will not rust and rot like that, they'll get a quick layer of superficial rust and then stop. These were even powder coated and looks like rust bubbled up through the coating, then stress/fatigue set in. Millions of cars and trucks have uncoated springs and do not rust through and snap in that manner, eg most leaf springs and factory coils on older cars/trucks are not coated and you hardly ever see them rust through or break esp after only 4 years.

Betting there was a bad run of base stock at Eibach or something went wrong with the heat treating/coating process. Another thing could have been metal spring compressors used at some point with sharp edge and scored the metal. Odd they broke same time same place both sides, prior accident and sway bar impacted springs?

Had a nearly identical thing happen with a car I had with aftermarket springs. Both fronts broke exactly same time same place after going over minor parking lot speed bump. Close inspection revealed same type of rust and bubbling of powder coating etc. I lived in DC area at the time which was not much of a winter/salt zone and I seldom drove that car in winter anyway. Springs were made by H&R. Eventually admitted a bad run of metal/coating and replaced them for free. Kind of scary as this was a street/track car. There was obviously a problem with the base metal as it was rusted/bubbled thru the coating underneath a plastic sheath that was wrapped around one coil on each side.

Honestly I'd toss those shocks they look awful. I'd be surprised if you can get enough corrosion off them to turn the perch. Definitely contact Eibach and send them pics, maybe they give you a new set for free.

edit: google eibach springs broke rust, look a the images, this happens a lot unfortunately.

 

Maybe they broke bc of the amount of preload you have on them??

 

Coil springs are a wear item, they do not last forever. At the last get new springs from your shop of choice and have a local shop with a spring compressor install.

IMO, have them rebuilt and new springs installed. I bet you'll need new bodies and bearings at the very least on top of the rebuilds. Those shocks look like typical east shocks that never get cleaned or serviced.

 

You could always blame the tariffs on steal.
I think I would just replace both shocks and springs and be out another $1200 or more. The replacements will rust, and have to be serviced or replaced again.

 

Why did you quote my post?

I don’t disagree with anything you said.

 

This. Either contact your vendor and try to get replacement springs for free, or go for a different brand. King manufactures its own springs: https://downsouthmotorsports.com/c-1206915-coil-springs-2-5-i-d-coil-springs.html

 

Properly made coil springs are not a "wear item", and certainly not in 4 years. Agree with not reusing shocks unless rebuilt, likely need to be tossed.
