So I just recently replaced my rear axle wheel bearing and discovered two issues with my rear end.
First off it's a 7.5 with 3.73s stock on my 2wd 97 manual.
When I took off the diff cover to drain the fluid I saw that one of the gears was chewed up in some places. My truck has a jerky acceleration and I thought it could be something with my manifold or my injectors so I had Jiffy Lube treat both. It is still misfires at high rpms before I need to shift into higher gear if I keep it in that gear. I also have a loose gas neck hose that I need to tighten up so that may also be a problem. But back to the gear. I don't know if this gear can cause slippage while driving so I was asking here. Also is it replaceable? It's the small skinny gear farthest to the left.
Also I have a problem with my right axle. After I changed the axle bearing and seal I am still getting some free wiggle room for the axle to go in and out of the axle housing. There is still space for me to push the axle into the lock bolt but only slightly. Is the axle bearing and seal supposed to limit the in-out movement of the shaft? I might have installed the bearing incorrectly, didn't have anything of the exact diameter of the bearing so I have to use a pipe a little smaller than needed, and I can change it again if it's the problem. Thanks.
