When changing a tire on a Z71 Chevy Colorado, it’s generally recommended to place the jack on the frame rather than directly on the axle. The frame is a more secure and stable lifting point, and it avoids damaging components like the axle or suspension.

However, if the suspension travel is too much and the frame doesn’t lift the tire off the ground sufficiently, you can jack from the axle housing (not the suspension components themselves) for certain situations. Be sure to use a flat, stable surface to avoid slippage. Always consult your vehicle’s owner's manual for the recommended jack points, as it may have specific guidelines for both safety and vehicle integrity.
