- - What did you do to / for your E53 today?? (https://xoutpost.com/bmw-sav-forums/x5-e53-forum/78921-what-did-you-do-your-e53-today.html)

Cleaned and conditioned the leather.

Just finished changing out to a new set of NGK 4 prong/platinum plugs from the NGK single prong Iridium. Plugs were a perfect light gray/white with typical black around the threaded edge. Cleaned a few things put it all back together and the darn thing drives sweet. Accelerates through the gears flawlessly, stomp the pedal and it takes off smoothly. NO jerks, jams or junk. Stopped at the light and bingo, that dam vibration. Got home, crawled under the car, PRND but no movement with the brake. SO, I twisted the front drive shaft a quarter turn until it wouldn't turn anymore, and back and forth a few times, sure enough the trans axle works fine - twisting the rear shaft perfectly with each turn. While running I could feel no vibration in the front drive shafts or the tranny.
BUT something is vibrating the heck out of this engine. BTW, sprayed half a can of carb spray all over the intake area and around the injectors. No change in idle. I can't find a vacuum leak if there is one. I am completely baffled. BTW, this thing burns no oil. I used a pint during my last 835 mile trip to and fro Atlanta and averaged 22 mpgs.
IF it is the vanos, what type of noise should it be making if it's damaged? THe only thing I hear from this engine is the typical BMW injector tap, no rattles,no loud winning , just sweet exhaust note when I accelerate. Ideas? I really don't want to take it to the dealer.

Alignment re-check. Found 2 problems:
1. Some how the right rear camber set to max positive still shows -3* :(
2. Left front inner and outer tire-rod seized as one piece.

Carb cleaner doesn't always find a vacuum leak. a pressurized smoke test is best route. Have you checked for error codes? Do I understand correctly that you can feel the vibration when transmission is in park and neutral?

Hi Tam! Welcome to my alignment from July.

I zeroed out the toe in rear for now as I don't feel like doing a rear suspension rebuild yet.

I replaced tie rods with Meyle HD for 120 shipped from FCP euro and took an hour and a half of my time, prior to the alignment.

Replace right front air spring and sway bar link .No more waking up to right front drop.

A crisp, sunny South Carolina morn, a twisting two lane road with no traffic... I couldn't resist... I HAD TO let her run! By the time we were done, we both had smiles from ear to ear...

Then I parked her in the west lot of Plant Spartanburg, to bask in the warmth of the sun with her sons and daughters and cousins... :2thumbs:

True story BTW!!!

:bustingup Same story here in MN lol!

After two weeks of delays and over two years since the last one. Getting it done at a local St Louis race shop.

Waiting for the winter to end and the City to repair all the potholes before I get the X align.
