I have an 08. So far I've replaced the front and rear stabilizer links, front control arms and lower ball joints, rear driver lower control arm, rear driver shock absorber, lock actuators in both side doors. And just yesterday, the alternator. I'm about to do the brakes and rotors all around as soon as it warms up a bit outside. And the rear assist arms. And an oil change. Then all I have to do is find out what's causing a parasitic draw. I've narrowed it down to the shunt fuse, still have lots to figure out.
FYI, you are not suppose to put anti-seize compound on spark plugs with silver colored threads. If the plug threads were dark colored, then you would need the compound. There are videos that discuss this point.
Well I just did some work on that van the other day for the owners and those coils are still working just fine and they put about 30000 miles on the van since I sold it to them. So in my opinion they're worth the risk if you can stomach replacing them again if they're faulty
