The Nissan Hardbody Pickup (D21U) Differential Seal is designed to lock in the critical gear oil within the axle. It also prevents dirt from getting in, resulting in sharp torque delivery around corners. The Differential Seal is a synthetic rubber responsive ring that fits over the shafts. This flexes with the heat but is firm enough to stop the leakage of 75W-90 onto the road. For the entire length of the production run, owners of any Hardbody Pickup (D21U) trim, 4x2 daily cruiser or 4x4 trail star, can install a common Differential Seal dimension brand quality assured. Open differentials and limited slip units rely on the same unyielding barrier because a leaking Differential Seal would drain lubricant, allow dirt in, and create friction that burns bearings. The Differential Seal maintains a stable oil film that reduces whining of gears and chatter from clutches, enhancing the efficiency of the driveline and lowering cabin noise. The Differential Seal ensures driver safety as it cools the wheel ends of a Hardbody Pickup (D21U) while preventing sudden lockup that tends to destabilize the pickup's light rear during gravel braking. With material choices such as everyday nitrile and heat-taming fluoro-rubber, every version of the Differential Seal fits securely and snugly into the housing, ensuring no guesswork during service. This intelligent interchangeability, along with the already famous steel boxed frame of the Nissan truck, makes the Differential Seal a little yet extremely important hero in the rugged born heritage of the Hardbody Pickup (D21U). Ever since the initial launch in 1986 until the refresh in the late nineties, the dimensions kept by Nissan were similar so that the parts bin stayed friendly. Nissan can use the same seal on a 1997 Nissan as on a 1987 Nissan. It shows Nissan's estimating know-how has ensured that every Hardbody Pickup (D21U) uses the same architecture so that the beloved Hardbody Pickup (D21U) is ready for miles ahead.
