Hi everyone, I recently purchased a used 2017 DS90X. I was able to work the price down because the rear axle had some movement, indicating to me it required new bearings. While taking it apart, I was surprised at how easy the axle slid out. The axle is not old and worn, its a light to medium used 2017? Slid new bearings on and they are not a snug fit throughout the entire center of the axle, not just where they will sit? I can wiggle the new bearings on the axle, I thought there should be no movement, nice and snug?

Axle measured 1.175", the old and new bearings inner ring measure 1.176-1.180.

Any info would be appreciated!

Thanks

I don't know those bikes, but I think you're right to want the bearing to be "gud-n-tite" against the axle..... guess I'm curious as to how "lightly used" was the replacement axle? Can you get a spec on the OD of a new axle where that bearing rides?

My bad, the ATV is a used 2017, not just the axle. I assume the axle is an OEM and has never been replaced.

Yes, bearings are not press fitted on the axle but, I didn't expect them to wiggle on the axle?
Thanks

Are the bearings you bought OE ?
Aftermarket brands are known to be sloppy ( for my bike at least ).
I learned my lesson with the last set of front wheel bearings I bought :rolleyes:

Not OEM, I purchased Pivot Works bearings. They are a tighter fit than the OEM bearings I'm replacing on the axle. The axle slop I believe was coming from the old OEM bearings inner diameter not being snug on the axle, once removed and I spun them, there wasn't the typical grabbing you get from bad bearings. I'll call the dealer and buy some OEM's to be sure.
Thanks

i agree with Bonzo on this. i don't have a ds90 but can am is known to have a few Oem parts that are a must on the bigger machines as all the after markets are junk, wheel bearings and tie rod ends to name a few. hopefully this solves your problem and I'm interested to see if thats the case.

Ok, new OEM rear axle bearings in hand. Unfortunately, the Inner dia. measures 1.177" as well:(
The dealer checked out the old bearing, the new after market bearing and the new OEM bearing, sliding all 3 to the middle of the axle where there is no wear n tear. The 2 new bearings were equally sloppy, old bearing was more sloppy.
They are going to reach out to BRP to see if there is any issues with the 2017 axles.

I just did the rear wheel bearings on my bike Sunday .
My rear half shafts are OE and my front half shafts are from CV man in Jessup .
I did the fronts just this spring .
The 4 bearings I bought ( at once ) fit much tighter around the OE rears than the aftermarket front axles .
I never even thought to put a mic on them :( .

I'll try and measure the slop later and post. Did your bearings have any side to side wobble on the axle?
Thanks

Local dealer heard back from BRP, they stated its most likely I need a new axle due to wear. I would agree with that if the bearings weren't sloppy in the middle of the untouched portion of the axle:mad:

Anyways, I measured the side to side wobble of the bearing on the untouched portion of the axle, it's .032"
Untouched portion of axle = 1.175"
Worn part of axle, bearing seat = 1.174"
Inner diameter of new OEM bearings = 1.177"

I'm going to try and find a slightly smaller inner diameter bearing locally or wrap the axle with some high speed aluminum tape where the bearings seat on the axle??
Thanks
