Dang!! I had one of my fully forged rears(2+ months old) 22x12 crack in 3 different places. We've got bad roads here as well in some places. What PSI do you run? I was curious if running a little lower would soften the blow

No.. I've run them as low as 40, and as high as 50. Doesn't seem to matter.

The roads here in Southern Belgium are worse than war-torn Afghanistan roads... The worst I've ever seen.

....And this is coming from a guy that has been to 45 of the 50 states, and over 70 countries in his life.

Washington DC? LA? Philly? They've got NOTHING on the shitterific roads in Southern Belgium.

Hell... I took a 14-day road trip on the motorcycle through 8 countries in the Balkans last Summer.... Even BOSNIA & KOSOVO have better roads than Southern Belgium.

Wow! I guess the weight of the X5 and potholes... it may be bound to happen. Crossing fingers to last more than a couple months this time. And I upsized the ratio 275/40 315/35 to maybe help with this and this is exactly when the crack happened

Thank you for the pics and details on the front and rear diff fluid change! Hopefully the royal purple has some added protection. Pretty sure my front diff is shot at 77k miles on my m50 (bought the car second hand).

I wouldn't say it's "shot". It depends. I was beginning to notice a bit of "shuttering"... particularly in reverse.... with the wheels turned either direction.

I changed the xfer case fluid... and the problem is GONE.

Now... I imagine that had I continued to drive like that for an extended period of time? Yea... I would have thrashed my xfer case.

All the experts say to do it at 50k miles. Yet, BMW says to do it at 100+k miles.

I trust the experts. It's $40 for the fluid.... it's worth the investment.

The diffs?? Ehhh... I just did them because i happen to be under the car. I figured, why not?

Car wash day. Can't believe I've had this thing almost 5 years now.
