Has anyone rust proofed their NX and experienced squeaks in the suspension a few months afterwards? Started noticing the noise this week when the temperature warmed up while going over speed bumps.

 

This is weird... I always was under the impression that the oil they use would lubricate parts, not dry them. Your issue sounds like a bushing. Are you 100% sure this is the cause?

 

Will be taking my car to the dealer to have them look at it......i did some research over the weekend and apparently oil-based spray such as Krown rust-proofing can damage rubber components such as those on door seals and the ones in the bushings.......was not aware of this what so ever. has anyone rust proofed and had any issues on this forum?

 

I am currently having this issue with my 2017 Ford F250. I took it in to the dealership because of a clunking in the rear end. The dealer called me and said the truck needs new rear shocks and bushings because of Krown contamination. Ford will not honor my warranty and the dealer wants $2,300 to fix the issue. I'm so disgusted right now! 🤢🤢

 

I am amazed at the amount of people who still rust proof their car.

 

would this be the same for the corrosion free 3000 rustproofing? ive used it on all my cars and never heard of this happening. Maybe because its a gel based lubricant?
