A few thoughts:
The upper control arm ball joint is not serviceable, you have to purchase the whole A Arm and it comes with both new bushings.
Left & right
upper control arms are the same, so one part number fits both sides
Left & right
LOWER control arms are different, so there are different part numbers for left and right sides
FYI, TRW suppled the OEM A arms. TRW & Moog are both good parts,
do not buy Crown parts, they are junk.AutoZone lists the upper TRW A arms: TRW Control Arm JTC1585
Moog is another good replacement option, RockAuto has a good selection of control arms and ball joints with reasonable prices.
Amazon and Summit Racing also lists some of the parts, so there are plenty of vendors selling good parts.
NAPA is another good place to check.
Unfortunately, IDParts only list Crown lower control arms, don't buy them, they don't last.

Quote:
HINT: A little trick when replacing control arms; always leave bushing ends slightly loose until you have the full weight of the vehicle on the control arms so they are setting at their normal at rest position. Then tighten the bushing end mounting bolts to specified torque.
If you tighten the bushing end bolts with the arms at full droop while setting on jack stands or on a lift; when you place the vehicle on the ground, it places the rubber bushings in tension at all times in their normal at rest position.
