Xoutpost.com - What did you do to / for your E53 today??

If the hum changes in left vs right curves very likely wheel bearing. You can't tell left from right side based on which curve makes it sound better because there are four zones of race that are involved (inner, outer, and top and bottom of each).

I've discovered that swapping between 255 and 235 tire will flip the race loading from inner top, outer bottom to outer top, inner bottom and can be a fantastic was to determine which wheel is at fault. It can be painfully difficult to determine which wheel is the cause.

That said, if the sound only is at speed,
You could just have a minor off balance that is finding a harmonic frequency of something

Hmmm.

I've changed six so far between our two X5 and one is overdue i have the part just not the time.

Swapping to the spare tire was the best confirmation of failure in my case. The 255 was silent bearing and when I put on the 235 it instantly howled like a wolf.

This car is newish to me a (a year this month) and I don't drive it much. The pics I posted here are from just one cylinder. I haven't ever seen this before. Loose plug? Even the coil pack was saturated. It always ran fine with no CEL. Your thoughts? :popcorn:

I put Ruthenium plugs in my M54. No noticeable difference. No change in fuel mileage either.

You have a badly leaking valve cover gasket.

Transported a 40' ladder 80 miles.

I cut a tenon using the tow eye as the mortice and that couldn't have worked better! I took some canvas strap wrapped around the ladder and screwed to the upright. I attached the ladder so it was slightly higher than the front roof rack so I could snug it down right.

Great idea. I'll need to keep that in mind for long lumber loads. Some of the rough cut stock I buy can be 16 feet long and the front of the boards really get to flopping around in the wind.

Anyone tried carrying some of these longer lumber/pipes the way plumbers used to by strapping them center line underneath?

That was my original plan for the ladder.

My roof rack is made from unistrut rail so I can hook on clamps for most sizes of tube. Also have spring nuts for 3/8 and 1/2" and the corresponding angle brackets makes the rack very versatile.

Did somebody say trellis? This one was 14 Ft x 8 Ft. Notice the roof crossbars lost their inherent upwards bow.
