I am working the list of service and repair items listed in the FAQ here and have a few questions,1.I retightened the rear axle bolts but could only turn them 35-40 degrees past where they were with a 4ft.power handle and my 240# jumping on it,greased and everything.I hope this is enough.2,Is spark plug changing,retorque something I can put off a while on a 2007 or needed to be checked now?3.same for valve adjustment,retainer check since it is an AP2?4,After checking all under car bolts tightness I noticed the alignment holes on both front and rear cradles are not perfectly aligned,close,but not perfect.Is this worth the effort since the wheel alignment is in range on both ends?Thanks in advance for any help.

 

how many miles? the OE plugs should last close to 100k miles. if the car drives fine then its not necessary to change unless you suspect something. VA ( valve adjustment ) only needs to get done once. i would just get that out of the way, besides it makes your car feel great after. as for the subframe bolts, i would not take them out if its not necessary either. if your alignment is fine then leave it be. from what i read new bolts should be used once they are taken out and can be PITA to put back in. but aligning the subframe isnt hard. as for the axle nut it should be fine if you managed to move it that much already.

 

my '04-05 service manual (so this may not apply to you) says to change the plugs at 100K OR every 7 years. you are coming up on that 7 year mark.

 

i had one of my plugs work its self loose i would atleast pull them and check them out if they look okay then re-install them and re-torque them. or replace them they are like 10 bucks each
