I am in the middle of the replacing my drivers front hub. The hub came surprisingly easy but when I got it off I didn't expect to see so much grease on the hub and inside the knuckle. Is this normal? Also the shaft has about 1/8" play up and down, I'm pretty sure when I searched the forums on this that seemed pretty normal but since there is a ton of grease in there it's got me second guessing myself. I have included some pictures.
In addition the seal that sits in the axle tube is trashed, but I don't have the tools to tear things down to that, would I be damaging my new hub by installing it and having a shop replace that axle tube seal?
Thanks
Looks like someone has liked packing the grease in there. Probably too much. Maybe someone has been adding the grease thru the abs sensor hole. You can clean all that grease off and make sure you add new stuff, but not that much(as in the pictures)
The shaft, yes that is normal. The shaft rides on the bearings in the hub, to help take out the play.
The axle tube seal is pretty normal. From what I hear that is an outer ring on the seal and they tear off and do not bother the seal itself. Mine have been like that for atleast the 1.5 years that I have owned it. No problems thus far. I have taken off the hubs to lube the needle bearings a year ago and have noticed them like that then.
Thanks for the reply Wallz, I ended up putting the new hub on after cleaning everything up as I needed the truck. I spent the last night searching the forums again for information. I had already had Guzzles' page bookmarked and used his for reference, that is why when I saw how much grease was in there I was taken aback.
I have always had the truck serviced at the Ford dealership and then at one or two shops after that. Never has any of them said anything about "packing" the hubs. I know there are two opinions here for and against using the ABS hole to run some grease into the area.
I am going to replace the knuckle seal and ball joints after reading all 29 pages of Racerguy's write up on ball joints. I was concerned that it would require a shop for the tool for the seal but also found a "how to" for a homemade seal driver. I just have to buy some more tools for that job.
