Wow amazing. Thank you
Yes I also have this noise. I wonder if it is related to the rear diff. I recently swapped out my rear diff fluid and still have the noise. Inconito and A.Hayes have describe my problem exactly.Not to hijack this thread, but I have had this same vibration on decel only for several years now. Seems to come and go a bit, and I've noticed it more in recent warm weather. I have low levels of "normal" RSN, but as incognito noted, this is only when the throttle is released, and seems kind of like the Sprinter version of a big rig engine braking. I have wondered if it's more of a torque converter/tranny thing, or driveshaft and rear end issue.
When I had the van at Upscale a while back, I had them take a quick look. Nothing visually conclusive, and since it's really mostly an annoyance, I opted out of a more involved (i.e., more expensive) diagnostic that would have required disassembling things. That was probably a year or more ago, and the condition doesn't seem to have gotten worse, but defintely still there. Any input is appreciated.
Europarts SDI just purchased a 04 with 143k and found the boot missing but don't want to replace the whole thing. Does anyone know of a size or place I can purchase just the joint boot? Great write up!
