Parts for your 2008 Nissan Maxima-Thrust bearing

2008 Nissan Maxima thrust-bearing — what it is and how to look after it

Yes, a thrust-bearing is absolutely relevant to the 2008 Nissan Maxima. Technical references that confirm this include the Nissan Factory Service Manual (FSM) for the 2008 Maxima (Engine Mechanical, VQ35DE, crankshaft/main bearing section), which specifies a thrust-type main bearing that controls crankshaft end play. Nissan’s parts catalogues also list a main bearing set with thrust faces for the VQ35DE. While this Maxima runs an Xtronic CVT (so there’s no manual clutch release/throwout “thrust” bearing), the engine itself uses a thrust-bearing, and the CVT contains internal thrust elements that aren’t routine service items.

On the VQ35DE, the thrust-bearing is integrated into one of the main bearings and keeps the crankshaft from shuffling forwards and backwards under axial loads. Those loads come from things like torque converter thrust, accessory belt pull, and drivetrain transitions. By holding the crank in the right spot, the thrust-bearing protects the block, keeps the oil film stable, and helps the rear main seal live a long life.

It’s not a regular service item, but it’s worth keeping an ear out as the kilometres roll up. Telltales of excessive crank end play can include a faint knock or scrape that changes with load, visible fore–aft movement at the crank pulley, erratic idle when shifting from Park to Drive, or glittery engine oil. If there’s any doubt, a technician can measure crank end play with a dial gauge and compare it to the FSM spec.

If replacement is needed, expect a proper bottom-end job. On the VQ35DE this typically involves removing the sump and structural lower pan/girdle, loosening main caps, and replacing the graded main bearings with the correct thrust pair, then checking oil clearance (often with plastigauge) and re-measuring end play. Many workshops prefer to lift the engine or drop the subframe for access. It’s a job best left to experienced techs with the FSM on hand for torque sequences, bearing grade selection, and sealant procedures.

Good habits help the thrust-bearing go the distance:

• Stick to quality oil and timely changes to protect the bearing surfaces.
• Avoid aggressive rocking between Drive and Reverse when stuck.
• After transmission or engine mount work, ensure alignment is spot on to minimise unwanted axial load.

Does a 2008 Maxima have a thrust-bearing?
Yes. The VQ35DE engine uses a thrust-type main bearing to control crankshaft end play. There’s no manual clutch release bearing because this model runs a CVT, but the engine thrust-bearing is very much part of the design.

What symptoms point to a worn thrust-bearing on a 2008 Maxima?
Look for fore–aft movement at the crank pulley, light knocking that changes with load, metallic glitter in the oil, and odd behaviour when shifting into Drive. A dial indicator check of crank end play against the FSM spec confirms it.

Can the thrust-bearing be replaced without pulling the engine?
Sometimes, with the subframe dropped and lots of room underneath, but many workshops choose to lift the engine for proper access to the structural lower pan/girdle. Either way, it’s a precision job that follows the FSM steps for bearing selection and torque procedure.
