Hi all. I started having the front and rear suspension bushings, etc. replaced on the wife's 2001 XK8 convertible, The work I have had done thus far has really improved the ride and handling. I need to continue the work on her car and start the same on my 2006 XKR convertible. Most of the part numbers are the same between the 8 and the R. Listed below is what I have compiled thus far.

My questions are:
1. What important parts am I missing that should be replaced?
2. Are any more critical than others?
3. I think all parts listed as the same between 8 and R are correct. Can anyone let me know if this is not so?
3. The shocks on the XKR are still in decent shape (just rolled over 48,000 miles). Is it worth replacing the shock bushings now?
4. Ball joints at last service on each were still in good shape. What SHOULD be the expected life for these?

XK8 ONLY

Rear suspension:
CCC6782 - Bushing, lower shock, rear, 1 each side

XK8/XKR

Front suspension:
MJA2105AG Stabilizer bar link, front, 1 each side (completed on XK8 -- this made a big difference, seemed easy to replace and are not expensive!)
MJA1462AB Bushing, upper control arm, front, 1 each side (completed on XK8)
MNE1360BB Bushing, lower front suspension control arm (wishbone), front, 1 each side (completed on XK8)
MNE1360CA Bushing, lower forward front suspension control arm (wishbone), front, 1 each side (completed on XK8)
MJA2102CE Bushing, stabilizer (sway) bar (clamps on), front, 1 each side (completed on XK8)
MXD2102AA Bushing, stabilizer (sway) bar, front, 1 each side
MJA2153AB Bushing, lower shock, front, 1 each side

Rear suspension:
MJA3502DD Bushing, stabilizer (sway) bar (clamps on), rear, 1 each side (completed on XK8)
MNA3504AB Bushing, stabilizer (sway) bar end link, rear, set of 2 each side (completed on XK8)
MJA2595AC Mount, subframe, rear, 2 required (cross-member bushing)
MJA3715AB2 Bushing, differential mount, rear, 4 required

 

l think MJA 1462AB should read X4 each side. There are also some differences for R performance cars in stabilizer bar rubber but that is not a criticism of your list.
