Four-bearing kit for the Jatco JF011E / RE0F10A CVT, the pulley and shaft bearings that cause the classic whine in 2007-2011 Altima, Rogue and Sentra.
A 2007-2011 Nissan Altima 2.5, Sentra or 2008-2011 Rogue that starts to whine or howl as the car picks up speed, with a fluid level that checks fine and no slip, very often has a tired pulley bearing inside its JF011E CVT. Nissan calls the same transmission the RE0F10A. This kit gives you four bearings for that job: three deep groove ball bearings stamped B45-108, B60-57NXUR and B40-210UR, plus a cylindrical roller bearing. It is meant for a shop or a capable home builder who already has the unit on the bench.
The JF011E has no gearsets for ratios. Instead, a steel push belt runs between a primary pulley driven from the engine side and a secondary pulley that sends power to the final drive. Each pulley is a pair of cones on a shaft, and hydraulic pressure squeezes those cones together hard enough to grip the belt. All of that clamping load, plus the belt tension, lands on the bearings that hold the two pulley shafts in the case and side cover. When a bearing race pits or the cage wears, the shaft starts to run slightly out of line. That is when the noise starts, and if the job is put off, the debris it sheds travels through the fluid and into the valve body and the belt.
Sonnax notes that CVT bearing failure is widespread and that fluid level and pressures usually look normal while the whine is present. Their road test is simple: hold a steady speed where the noise is loudest, then select a lower ratio manually so engine speed rises. If the noise climbs with engine rpm, suspect the primary pulley bearing. If it stays the same, look at the secondary or final drive bearing. They also point out that a damaged bearing can let the shaft run off center and wear the secondary pulley input seal, which then shows up as low secondary pressure. A drone combined with slipping and flare is a different problem; our CVT slipping under load guide covers that split, and the Jatco CVT Nissan problems guide lists the other common RE0F10A failures to rule out first.
The listing covers the Jatco JF011E / RE0F10A in 2007-2011 Nissan Altima and Sentra, 2008-2011 Rogue, 2007-2011 Jeep Compass, Mitsubishi Outlander and Galant, 2009-2011 Renault Koleos and 2010-2011 Suzuki Kizashi. The catalog line also names V6 and Hybrid trims. Jatco built the JF011E for four-cylinder engines, and the V6 Nissans use a different CVT, so check the transmission tag before ordering: it should read JF011E or RE0F10A. Bearing positions can differ by revision, so compare the numbers stamped on your old bearings with B45-108, B60-57NXUR and B40-210UR, or send us your year and VIN and we will check it. Other parts for this unit are on our CVT parts page.

If the whine comes from the pulley bearings, yes. Confirm it first: at a steady speed, drop to a lower ratio manually. Noise that rises with engine rpm points to the primary bearing, and noise that stays the same points to the secondary or final drive side. If the belt or cone faces are scored, you will need those parts too.
The JF011E was used behind four-cylinder engines. The V6 Altima uses a different CVT, so look at the transmission tag. If it does not say JF011E or RE0F10A, this kit is not for your car.
Three deep groove ball bearings stamped B45-108, B60-57NXUR and B40-210UR, plus one cylindrical roller bearing. Compare the numbers on your old bearings before installing.
No. The pulley bearings sit in the case and side cover, so the unit has to come out and the pulleys have to be removed. You need a press and proper drivers.
Use Nissan NS-2 CVT fluid in Nissan applications, or the CVT fluid listed in the owner's manual for Jeep, Mitsubishi, Renault and Suzuki models. Check the level hot with the engine running and reset the CVT adaptives afterward.
A new filter and pan gasket, the pulley piston seals and gaskets from a rebuild kit, and the push belt or pulleys if the faces are worn. Flush the cooler so old bearing debris does not get pulled back into the unit.
