Default LS460 Could you help me with this one part?

Hi guys,

I'm going to replace upper rear differential mounts in my 2007 LS460. I need help with finding one part, which is the part described as N01 (I circled it in red). Could you please help me? I cannot find part number and I don't know what to do.

It appears the "NO1" part is the complete assembly of the 4 pieces below it. Try checking these part #s with other sources to verify they are accurate and up to date,

N01 is explained at the top of the diagram, and it suggests that this isn't a part you can obtain. I'd guess that these pieces might be pressed in to the differential housing? Then, N04 on the housing itself just says that they don't offer that assembly as a part. However, then the combination of the two has a number (41102B). I was unable to turn this into a full part number when looking at the charts, but one possibility is that the housing+installed mounts assembly is available somewhere. I'd doubt that you can get separate OEM mounts though; I'd guess this is like the control arm bushing situation where they only sell them installed in new control arms, though some third parties sell separate bushings if you want to try pressing the old ones out and pressing new ones in. I'm not sure if there are any third parties for these parts though.

Also, while it is a little unclear, I'm reasonably certain (for a number of reasons, including looking at the assembly diagram of the differential in the repair manual) that the dotted lines going to the four pieces below is not an exploded diagram of the "N01" part, but instead it shows where the N01 differential mount is stacked amongst the various bolts and stoppers: sandwiched between the two upper and two lower pieces. So from bottom to top: bolt, lower stopper, differential including mount piece this thread is about, upper stopper, washer*.

*not 100% sure about this top washer. The assembly diagram for my 2014 does not seem to show such a washer. If the "※1/2" notes are referring to model years then that could explain it, though if that was the case I'd expect the "1110" part to be ordered "1011".

DOH! Looks like you're correct, and that piece is part of the differential assembly.
