The passenger side bearing on the front deferential of my 97 K1500 seems to be going out. When I rotate the passenger side front tire (after freeing up the disk brake) I can hear a grumble and when I fell around, it seems to be coming from the end of the extension tube on passenger side of the differential. I also have a small leak on the seal on the driver side. I have not had one of these apart before, so I am looking for some advice from anyone who has.
Questions: If I have to work on both sides of the differential, is it better just to drop the whole thing out or better to work on it in place? I can not tell from the exploded view in my shop manual if the bearing at the end of the extension tube is a sealed bearing or if it is lubricated from the differential. Can anyone tell me? If it is not a sealed bearing, I assume it is like the bearings in the rear differential and the inner race is the output shaft itself. If this is the case, what is the chance that this shaft is not damaged? I checked .... it costs about $400.00. If the bearing is really tore up, should I plan to split the case to clean out any metal particles?
Any other advice on how to go about this job would be appreciated.
