Chevrolet El Camino Differential Seal
Chevrolet El Camino Differential Seal ensures that the gear oil remains locked inside the rear differential. It also prevents dirt from getting in. As such, you have smooth power delivery with every bend in the road. Located at the point where the housing meets the drive shaft yoke, the Differential Seal is a small ring of synthetic rubber that forms a tight barrier to prevent the lubricant from leaking out or contaminants from leaking in due to pressure, heat, and moisture. The oil keeps gear contact for open and limited slip diffs that allow the wheels to spin at their own pace when cornering. If oil runs low, the diff will start to clank and handling problems will appear. Earlier Chevrolet El Camino models equipped with open diffs relied on the same basic single-lip style seal. This Differential Seal simply hugged the rotating pinion. Later models fitted with limited slip units usually received a much tougher dual-lip Differential Seal. This newer design was able to handle the greater clutch pack heat and the higher internal pressure. The difference was an added sealing ridge and tougher rubber compound. No matter how they look, when a Chevrolet El Camino Differential Seal starts leaking or rattling, it must be replaced right away when the vehicle arrives at the workshop. Replace it with a new one and make sure to grease it properly and refill with the right fluid, which is 75W-90, to restore quiet operation and prolong differential life.

Chevrolet El Camino Differential Seal Parts Questions & Experts Answers
- Q: How to replace the differential seal on Chevrolet El Camino?A:To replace the pinion oil seal on a vehicle, first, place the vehicle over an inspection pit or raise the rear end to provide working clearance. Disconnect the driveshaft and tie it to the body sideframe to prevent it from sliding out of the transmission. Use a torque wrench to check the torque required to rotate the pinion and record this for later use. Scribe or dot punch alignment marks on the pinion stem, nut, and flange for proper reassembly. Count the number of threads visible between the nut and pinion stem and record this as well. Use a suitable tool to hold the pinion flange still while removing the self-locking pinion nut. Unscrew and remove the nut, then withdraw the companion flange using a two or three-legged extractor if necessary. Do not attempt to lever behind the deflector or hammer on the pinion stem. Pry out the old seal and discard it. Lubricate the lips of a new seal with lithium-based grease and tap it into position, ensuring it enters the housing squarely and to its full depth. For installation, align the mating marks made earlier and install the companion flange, using a spacer if needed. Apply a non-hardening jointing compound to seal any oil seepage. Install the thrust washer and nut, tightening the nut carefully to expose the original number of threads. Measure the torque required to rotate the pinion and tighten the nut slightly until it matches the recorded figure. To compensate for the new oil seal, further tighten the nut so that the rotational torque of the pinion exceeds the recorded value by 1 to 5 lbs-in. Reconnect the driveshaft, install the brake drum and wheel, and lower the vehicle.
