I have a 92 ford f250 2wd that has bearing sound coming from driver side front tire. I replaced the tapered roller bearings and is still making the same sound. I noticed the spindle had some discoloration where the interior bearing sits. I also went back in a few months after I replaced the bearings and the grease on the interior bearing had darkened significantly where the outside bearing's grease seems fine. I am wondering if misalignment or bad coil springs or shocks could cause the interior bearing to wear? Thanks.

More than likely the torque on the bearings is too low or too high. The grease turning dark is caused by heat. So if the torque on the nut is not correct it will cause excess heat because the bearing is not spinning straight or it is too tight and causing excess friction.

I attached the info about replacing them and adjusting them. Let me know if you find they are not torqued properly. Also, if the spindle has signs of wear it may need to be replaced as well.
