The axles are out and new U-joints are installed, so I’m about ready to install it all with new wheel hubs on both sides of my ‘89 Laredo.
First thanks for all the great info on this forum it really helped this project.
First question: I noticed when I pulled the passenger side axle – no vac disco - it looked a little “wet” to about 12 inches from the tip of the axle (where it goes into the differential). It has not leaked out on the street but my guess is the seal is going and I need to replace it?
Second question: When I install the spindle through the hub there is a flange that seals up the back of the hub do I pack with grease or install dry? If greased can I use synthetic - as I just purchased a tube?
Third question: The Napa U-joints have grease fittings. Can I use synthetic grease...would mixing synthetic grease and “real” grease create a problem?
That’s all the questions. Just wanted to add that I’m replacing both hubs but only one was shot! It’s amazing that one hub seems fine after 17 years and 193,000 miles...that’s says lot about our Jeeps. Also the original U-joints were fine but I figured the axles are out so I might as well replace the buggers.
Thanks,
John
