P1000 Clunk sound when decelerating

[Marcel]

I’ve started to notice a clunk noise when I quickly take my foot off the accelerator of my 2018 p1000-5, mostly while driving over 20 mph. I just had my machine in the shop to replace a bad pinion seal in the rear differential. It almost sounds like, but not quite the same noise it makes while shifting.

The issue is I don’t remember if that clunk was there before it went in the shop or if I’m just paranoid now and worried something is not put together right.

Are others getting this noise on their P1000 or is there something loose on mine.
Thanks

I've never noticed any clunk in mine. Might sound silly, but check under your seat area and skidplate etc for a tool or part that may have accidentally been left from the repair. (Mechanic: "Where the HELL is my 13 mm deep socket???")

Not silly at all. I have worked as a mechanic all my life, have seen many tools "disappear" due to being left on a frame etc. and the tech heard something clank while on a test drive. Some have been fortunate enough to find them on the road on the way back, most not so lucky. 👍

I checked everything and couldn’t find anything loose. I went for a drive on the weekend and noticed it only makes the noise while in turf mode or 2wd. When in 4wd it wouldn’t do it at all.

Could be shaft play (movement) in front shaft (no homo NTC) hence only during Turf and 2WD

Probably a bit of a shot in the dark, but any drivetrain noise is worth an adjustment to your rear diff shift alignment. Most of them could use it anyway for faster and smoother engage/disengagement.

Follow this procedure, not the one in your service manual. Diff should lock and unlock within a half turn of the wheel.

I have seen a lot of posts about Pioneer's making a clanking/banging sound when shifting from 2WD to Turf Mode. I have made a video detailing how to fix this and what causes that. Please like and subscribe and I hope this helps some of you!

Took my machine in the garage for maintenance today and noticed the clunk again when turning the rear wheels. Turns out the entire rear diff was moving a few mm. The bolts were tight, but obviously not tight enough, now the noise is gone. 😁
