Unfortunately it's not the shock. Although there are many people with noisy rear shocks including mine with were replaced...Its not the cause for the clunk that people are experiencing. It is unknown if this is fixed in the 2022 f-150s. This is not isolated to the Raptor alone. It is present in highly optioned f-150's as well. The irony in this is based on the eminent recall, the noise originates from a drivetrain part that was designed to suppress sound entering the cabin. Apparently it has come loose on 180,000+ f-150s and hits the driveline on uneven roads causing the knock. It also has cause some owners drivelines to break which can create a pole-vault experience. Effected owners should be receiving recall notices in the next 20 days. Assuming Ford is waiting on these notices so that they can send instructions and parts to dealers to resolve expeditiously, shortly after we will know if it solves the problem. For those with 22's on order, it would be reasonable to think that because Ford is aware of the issue, and is hopefully sending parts to dealers ahead of the recall, that they may actually be resolving this on the production line. But that is a big assumption which from a practical matter could be contrasted by supply chain. It may be easier for them to knowingly produce a defective truck, ship it to recognize revenue, and have the dealers resolve the problem through the bulletin.
