X5 4.8 integral link stripped thread

[svvg]

Thanks. I think the car spent most of its life in and around Cambridge (UK). We have 5 bmw's in the family and I work on my friend's cars too - two 2002 E46, a 2006 e92 a 2007 130 and 2005 E46s too. All have lived outside in London/Cambridge - and while one of the 2002 E46s was a total bastd - the X5 is on another level re corroded and rusted fixings! I had to buy a replacement front under protection bar as mine fell apart when I removed the undertray! Also have big rust holes in the boot where, on an E46/90 the battery would go. The rest of the car is good though - and the engine is really strong!

Yep - I'd removed the swing arm bolt and upper control arms so the hub could pivot out as I used the puller to effectively push the hub towards me off the axle. Genuinely reaffirmed my belief in a deity when I managed (eventually) tonremove the handbrake cable!

We live Midwest USA and we use salt for ice control on the roads so the cars are covered in salt for about 3 months a year. The car companies wised up and started galvanizing a lot about 30 years ago and it's rare to ever see a rusted panel on a car. X5 uses a lot of aluminum so very little under body rust but galvanic corrosion is another problem to deal with.

Recently changing rear brakes on a brother's Ford focus, my normal 220 ft·lb impact wrench would not budge the lugs so I got out the beast 700-1100 ft·lb model and it was actually working to remove the lug nuts. Smoke even on some. Then on one nut it wouldn't even come off! Apparently galvanic corrosion between the steel lug nut and aluminum wheel bonded the two. If it was the threads only the lug should have snapped.

Penetrating fluid and 10 minutes of impact on and off finally broke the nut free.

Hub puller to push the CV out is slick. I've had to remove the axle about 8-10 times so far between mine and wife's x5 and only have had to use a hammer and rod of some kind (socket extension).
