2021 Nissan Altima Service and Repair Manual
The 2021 Nissan Altima is documented here as it left the line, right down to which engine sits in the bay — the 2.5L PR25DD four or the turbocharged 2.0L KR20DDET — so the specifications and tightening sequences you work to are the ones Nissan published for this year and trim rather than an approximation carried over from an adjacent one.

Known issues on the 2021 Altima. Two recalls are on federal record for this model year. The first covers the steering tie rod assembly: the tie rod ball joint fastener was not tightened properly, which could result in the tie rod ball joint detaching from the steering knuckle, and a detached tie rod ball joint can cause a loss of steering control and increase the risk of a crash. The second covers the rearview camera: damage to the camera harness can cause distortion or loss of the rearview camera display image, and a rearview camera that does not properly display an image can reduce the driver's rear view, increasing the risk of a crash; those vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard number 111, Rear Visibility. Owners have filed 69 complaints for the year, and no technical service bulletins are logged. The factory diagnostic and repair procedures behind both of those systems are here.
Whether you are checking tie rod end play and steering knuckle fastener torque, tracing a rearview camera harness fault, or working through a scheduled service on the PR25DD, the manual holds you to Nissan's own procedure and the correct value for this 2021 Altima.
