fit?\u003c\/strong\u003e\u003cbr\u003e\nThe YUKMK GM8.5 fits the GM 8.5in 10-bolt rear differential, one of the most prevalent rear axle assemblies across GM's truck, car, SUV, and van lineups from 1970 through the early 2000s.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eDoes this kit include bearings?\u003c\/strong\u003e\u003cbr\u003e\nNo. The MK GM8.5 is a minor install kit containing seals, sleeve, shims, and marking compound. Pinion and carrier bearings are sold separately through Yukon Gear's complete or master install kit options.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eCan I use the YUKMK GM8.5 for a ring and pinion swap?\u003c\/strong\u003e\u003cbr\u003e\nYes. It is an ideal companion for any ring and pinion swap on a GM 8.5in 10-bolt axle, providing all the consumable components required for a proper, leak-free installation.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eWill this void my vehicle warranty?\u003c\/strong\u003e\u003cbr\u003e\nUnder the Magnuson-Moss Warranty Act, a manufacturer may not void your vehicle warranty simply because you used an aftermarket part. They must prove the part caused the failure. Proper installation of the YUKMK GM8.5 should not void your warranty.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eHow do I know the correct shim to use for my pinion depth?\u003c\/strong\u003e\u003cbr\u003e\nUse a depth gauge or dial indicator to compare against the differential's nominal pinion depth specification. The Supershim kit provides a range of thicknesses so you can select the one needed to achieve the correct gear mesh pattern as shown by the marking compound.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eWhat pinion preload should I set for the GM 8.5in?\u003c\/strong\u003e\u003cbr\u003e\nFor new bearings on a GM 8.5in 10-bolt, pinion preload is typically in the range of 20-25 inch-pounds. Always verify with the service manual for your specific vehicle application.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eIs the MK GM8.5 the same as components used at the factory?\u003c\/strong\u003e\u003cbr\u003e\nWhile Yukon Gear components meet or exceed OEM specifications, the MK GM8.5 is designed for service and rebuild use. Factory assembly uses automated torque processes; this kit is optimized for proper hand-tool installation.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eWhat gear oil should I use after installing with MK GM8.5?\u003c\/strong\u003e\u003cbr\u003e\nUse a 75W-90 or 80W-90 API GL-5 gear lubricant, adding the appropriate amount of friction modifier if the vehicle has a Positraction limited-slip differential.\u003c\/p\u003e\n\n\u003ch4\u003eInstallation Instructions\u003c\/h4\u003e\n\u003col\u003e\n\u003cli\u003eLift and support the vehicle safely, then drain the differential fluid\u003c\/li\u003e\n\u003cli\u003eDisconnect the driveshaft from the pinion flange and mark the position for reinstallation\u003c\/li\u003e\n\u003cli\u003eRemove the pinion nut, pinion flange, and worn pinion seal from the housing\u003c\/li\u003e\n\u003cli\u003eRemove the original crush sleeve from the pinion shaft\u003c\/li\u003e\n\u003cli\u003eClean all sealing and bearing surfaces, inspect for wear or damage\u003c\/li\u003e\n\u003cli\u003eInstall the new crush sleeve from the YUKMK GM8.5 kit onto the pinion shaft\u003c\/li\u003e\n\u003cli\u003ePress the new pinion seal into the housing with the sealing lip facing inward\u003c\/li\u003e\n\u003cli\u003eReinstall the pinion flange and tighten the pinion nut incrementally while monitoring rolling preload\u003c\/li\u003e\n\u003cli\u003eApply marking compound with the included brush and check gear mesh pattern; use the Supershim kit to adjust pinion depth as needed\u003c\/li\u003e\n\u003cli\u003eComplete reassembly and fill the differential with the correct lubricant to the specified level\u003c\/li\u003e\n\u003c\/ol\u003e\n\n\u003cp\u003e\u003cstrong\u003eProposition 65 Warning:\u003c\/strong\u003e This product can expose you to chemicals including lead, which is known to the State of California to cause cancer and birth defects or other reproductive harm.
