Question:

Hello, we have a 2022 Adrenaline 21LT, suspension squeaks a lot. Would a wet bolt kit fix this issue? Can you recommend one? Thx

Hey Sean, a wet bolt kit like # MR46ZR is an excellent upgrade and would most definitely help with the squeaking issue, but it isn't an end all be all solution.

In reality, you'd need to lubricate all moving parts with silicone grease or lithium grease # L11316. If that doesn't fix the issue, then you might need to look toward replacing those components as they might be worn out.

In theory, lubricating those moving parts should not only prolong the life of those parts but also get rid of that squeaking. If you need anything else though, please feel free to drop a comment and let me know!

Hey Sean, how did things go after you tried lubricating the suspension parts on your Adrenaline 21LT? Did that take care of the squeaking, or did you end up going with the wet bolt kit too? Your update could make it easier for others dealing with the same noise.
