Yep....can get caught really easily..
Here goes, the others may well add to the list.
The front:
Make sure you know the difference between series 1 and 11 front ends. ( which series you need depends on your kit )
Make sure the front top and bottom arms are from the same series.
Make sure none of it is bent.
Check stub axle for seized bearings and wear.
The rear:
Check if the ratio is what you need. A tag attached to the diff will have a number like 43/13. thats a 3.31:1, there are quite a few different ratios.
Check diff seals for leaks. You may want to replace all seals anyways but really stuffed seals may indicate badly work internals. Oftenwise Jags are driven by non-enthusiasts who leave the hand brake on which cooks the diff seal. Then the diff runs dry and wares prematurely.
Mike the rotors. If they havn't been turned too thin you should be able to use them again.
When you pull the assembly apart keep note of where all the shims belong.
Rotate one axle .... if the other axle turns you have a Powr-Lok.
Check aluminium uprights for cracks.
Check aluminium uprights to ensure the wheel bearing hasn't siezed and rotated in the housing. The housing will be stuffed if it has.
If I think of more I'll add em.
