Default Seemingly rare issue, seeking input.

I've been chasing down a sporadic noise in my driver side rear end. Put it in the best local indy import shop for diagnosis. They called today & found that the "knuckle" on that side has a failing bearing/bushing, the bad part is that they do not have a press that's needed to do the job & can only recommend a Jag dealer, which is 3 hours away & horrible lol. What about replacing the entire knuckle as opposed to the bearing/bushing ?!

Anyone know of a way around this issue.

TIA

I am sure the real issue is not finding a press locally but rather having the correct tools to use with the press. You can find them here: https://www.jcna.com/tool-loan

There is no press needed, just punches to 'drift' the bearing races from the hub assy. and back in again (fulcrum or axle bearings).
Keep track of the shims!!

I'm going to get a better explanation in writing when I pick it up this week. Good news is they found the damn coolant leak that 2 other "shops" couldn't locate. Was losing 3-5 ounces of coolant every 500-600 miles with no visible clues. It was a hose on the bottom side of the engine.


Edit :

Anyone have a large printable diagram of the rear hub/spindle/knuckle I can take & get them to elaborate better. As I think terminology w/ them being life long southern guys is adding some murk to the picture.

There are 2 areas of BEARINGS in the rear hub assy.

The main axle shaft that holds the wheel uses 2 bearings, spacers and shims as well as a reluctor rotor for speed sensors.

The 'fulcrum' bearings for the lower control arm are also tapered roller bearings with spacers and shims.

Both sets can be replaced with common hand tools (hammers, punches and race drivers if you have a set).

New seals and bearings and you have all you need.

I have done DOZENS and DOZENS since my 'E' Type I bought in the early 1970s. Reuse original shims with new bearings/seals unless the entire hub has become damaged/destroyed.

Sounds great ! Anyone have a part # for these bearings ?!
I'm going to take a diagram there & have them mark which are needed. They threw me off using the terms "bushings & knuckle", we will sort through it in person, but I do not want them ordering parts as I suppose they will opt for the highest priced units when I can get the same spec for much less.

One would be surprised how difficult it is to find a labeled rear hub diagram that can be copied via print screen to MS Paint & still be legible when printed @ standard letter size. Even more surprising is how accomplished I feel after making this basic image lol. Going to run this by the shop & get them to mark what's having issues, also get them to re-evaluate the remedy process to dismiss the press notion.
