The attached video is from underneath the car at the shop.Do you need a whole new joint, or just the boot kit? They are much like a c.v. Joint. If the boot stays in good order, the lubricant stays in, contaminants stay out, and the joint operates for a long time. It hardly articulates at all, apart from tiny movements in the mounting bushings and carrier bearing cushions. A suppose if it has vibration, you already have wear and excess clearance.
I replaced my lobro boot a few years ago. That was when U-joint supplies were just running out.
If you need the whole lobro joint, consider going with a custom, 1-piece prop shaft to replace your OEM. I spent over half of what a new, stronger 1-piece would have cost to fully refresh my stock prop shaft. U joints are a known weak spot when combined with “enhanced” power levels, and they are no long easily available (or at very high price NOS).
This was taken after I drove it and found out there was basically vibration going uphill and rattling going downhill. Seems like two separate sounds. Upon inspection they discovered what's in the video. I don't know what's normal but I would prefer to not throw away any money. It is completely stock and so I'm not entirely concerned with needing a brand new driveshaft as much as I would love to. So I would ideally like to replace the boot or the whole joint as well as the carrier bearing if they have to take that out anyway and be good to go.
