A rear axle on a 72-inch X3 does not usually die in an interesting way. It dies because a boot tore on a stob three rides ago, the grease walked out, and the joint ground itself up without saying anything until it started clicking in a turn. Then the clicking becomes a bang, and you are winching a $30,000 machine onto a trailer over a part that costs less than a set of tires. The 4XPRO Rear Left or Right CV Axle for the 72" Can-Am Maverick X3 is the spare that keeps that from being a tow, and it is $129.
Fully assembled, out of the box
4XPRO describes this as a heavy-duty replacement rear CV axle built for hard trail, mud and work use, and the part that matters for the install: it is fully assembled with inboard and outboard CV joints and neoprene boots, so it installs straight out of the box.
That is the whole value proposition on a trailside part. A bare shaft means pressing joints, packing grease and clamping boots on a workbench, which is a shop job. A complete assembly is two nuts, a hub and a sway bar link in the dirt. It is also why this is the part to carry rather than the part to order — a spare axle in the trailer is the difference between a long afternoon and a ruined weekend.
The neoprene boots are worth a note of their own, since a CV joint almost never fails from torque on a stock-power machine. It fails because the boot opened up. Boots are the consumable; the joint is just what dies afterward.
The numbers to check before you order
4XPRO publishes the dimensions, and they ask you to verify them. This axle:
- Replaces OEM #705502362
- Measures 33" long when compressed
- Has 30 inboard splines
- Has 29 outboard splines
Those three measurements are how you confirm a fit without trusting a year range, and on the X3 that is genuinely useful. Can-Am built this platform in 64-inch and 72-inch widths through the same model years, and the wide-body cars take a longer shaft. If you have a 72-inch car, this is the axle; if yours is a 64, the part number is different and the length will tell you so immediately. Pull the old one, measure it compressed, count the splines, and you will know.
One more thing this axle does well: 4XPRO lists it as Rear Left or Right. One part number covers both sides, which halves what you have to keep on the shelf.
Fitment
4XPRO's list covers the 72-inch X3 and X3 MAX across the platform's whole run:
- 2017-2026 Maverick X3 72" — including STD, XRS DPS, TURBO R XRC / XMR / XRS, and the TURBO RR RS / XMR / XRC / XRS and XRS SAS cars
- 2017-2026 Maverick X3 MAX 72" — including XRS, TURBO R XRS, and the TURBO RR RS / XMR / XRC / XRS and XRS SAS cars
- 2019 Maverick MAX 64" TURBO R — STD Non Smart Lok, STD Smart Lok and R XDS Smart Lok, the one 64-inch entry on the list
Ten model years and most of the trim ladder, Smart-Lok and Smart-Shox cars included. The 2019 MAX 64-inch entry is on 4XPRO's list as written — if that is your car, verify the length and spline counts against your old shaft before you order, because it is the exception rather than the pattern.
Who it is for
Two owners, really. The one who is already down with a clicking rear axle and wants it fixed this week rather than next, and the one who is not down yet and knows better than to be caught out. At $129 for an assembled axle, the second owner is making the smarter purchase — a spare rear axle rides in the trailer with the tool bag and does nothing until the day it saves the trip. If your X3 lives in mud, keep an eye on the boots between rides; it is the cheapest inspection on the machine.
