    Un plug vacuum line from solenoid , put cap on solenoid port so you don't have a vac leak. Drive it, if noise is still there , you may have a hub bearing issue or bad Cv joint. If you don't have noise you have a leak in your lines or check valve it is partially engaging hubs when engine vacuum varies under driving conditions.

    Hello Tony. Vacuum line went to the IWE. Front wheel. My local mechanic tied in the old smoke machine after the vacuum check valve located along driver firewall. He may be able to explain better. His name is Will 702-463-0974. Mention Carlos w/ the Raptor.

    Those lines are going to keep breaking and cracking. If you plan to keep them, upgrade to silicone.

    Here is a video of the grinding noise , is not a constant noise if you drive “normal” is fine the noise only happens on acceleration like when you are going to pass someone

    Maybe someone has had the same problem thanks

    That sounds like something transmission related for sure. It could also be a transfer case issue; when mine went out a few days prior it was making some oddball noises. It failed in 2Hi so I was able to drive it around until the new one arrived at the dealership.

    Have you checked to make sure no heat shields are rubbing anything?

    Tony, the best check for this is to unplug the vac line at the solenoid—the one that goes to IWEs. Cap it at the solenoid. If it still makes the sound, in my opinion it sounds like a loose heat shield vibration.

    I already did that , that video was taken with the hose loose and the selenoid cap will recheck all heat shields thanks
