warranty?\u003c\/strong\u003e\u003cbr\u003e\nThe Magnuson-Moss Warranty Act protects you from blanket warranty denials caused solely by aftermarket part installation. Your dealer must demonstrate the part directly caused the failure in question.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eHow do I confirm my GM axle is an 8.5 or 8.6 inch and uses 30 splines?\u003c\/strong\u003e\u003cbr\u003e\nThe GM 8.5 inch and 8.6 inch 10-bolt axles are commonly found in 1999 and newer Silverado 1500, Sierra 1500, Tahoe, Yukon, and Suburban trucks. The 8.6 inch replaced the 8.5 inch around 1999. Both use the same 30 spline axle shaft. Count the splines on your axle shaft to confirm before ordering YGLGM8.5-3-30.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eWhat gear ratios are compatible with YGLGM8.5-3-30?\u003c\/strong\u003e\u003cbr\u003e\nThis Grizzly Locker requires a 2.73 or numerically higher ratio in the GM 8.5 or 8.6 inch housing. It will not fit the low-carrier break housing used with ratios below 2.73.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eDoes the Grizzly Locker work differently than a posi or limited-slip unit?\u003c\/strong\u003e\u003cbr\u003e\nYes. A Grizzly Locker is a fully automatic mechanical locker, not a limited-slip clutch pack. It provides 100 percent lockup under torque rather than a percentage of torque transfer. It clicks during cornering, which is normal.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eCan I install YGLGM8.5-3-30 myself?\u003c\/strong\u003e\u003cbr\u003e\nProfessional installation is recommended. Setting carrier bearing preload, ring gear backlash, and contact pattern requires specialized tools and experience. Improper setup can damage the ring and pinion.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eWhat fluid does the GM 8.5\/8.6 axle require with a Grizzly Locker?\u003c\/strong\u003e\u003cbr\u003e\nUse 75W-90 or 80W-90 full synthetic GL-5 gear oil. Do not add limited-slip friction modifier. If your vehicle previously had a limited-slip, flush the housing completely before installing YGLGM8.5-3-30.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eIs there anything special about installing this in a 4WD versus 2WD truck?\u003c\/strong\u003e\u003cbr\u003e\nInstallation procedure is the same for both. On 4WD trucks, ensure the front and rear differentials are in the same or compatible ratio. Mixing ratios in a part-time 4WD system can cause driveline binding.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eWhat warranty does YGLGM8.5-3-30 carry?\u003c\/strong\u003e\u003cbr\u003e\nYukon Gear provides a manufacturer limited warranty against defects in materials and workmanship from the date of purchase.
