I bought a 2004 Rubicon with 60k miles. Didn't notice at first, this being my first Wrangler, the noise from the front end. I thought maybe all jeeps were this loud. Replaced unit bearings 2 days ago. Still a gear whine above 30 mph. Changed front diff. fluid, which came out all silvery! I've seen a lot of posts which say, with a bad front diff, find a used one and swap.
My question is this being a D44 in a rubicon, is it worth fixing?
I suspect carrier bearings in diff. I noticed that the cover already had 2 colors of rtv which points to at least twice in 60k that someone has been into the front diff. Any suggestions? I've had jeep less than a month.
