rumble at 65mph on acceleration

[moss]

Hi, new to the forum, but just purchased a BMW 3.0D X5 2002 , lovely car, dream to drive, have a few issues, one is theres a rumble that appears at about 65-70 in top gear when accelerating hard, if you back off accelerater it goes away, if you change down it goes away, any ideas what this could be ? no warnig lights or lack of power...
ive got a EGR bypass mod off ebay as i was told this will make the car run better, i will fit this at the wkend, hopefully no engine management warning lights !
am thinking of a remap. as told this will not only give you up to 210bhp but improve mpg if you drive it sensibly... and lastly a clonk coming from front rh wheel,. ive managed to work out just that one wheel by using speed humps in local car park,. one wheel on , one wheel off lol.. hopefully just a anti roll bar or drop link, are drop link common fails on these ?
thanks in advance,there will be more questions ive no doubt, but wanted to start off with these

clock will be a bush, balljoint or drop link, the rumble could be a number of things

Hello moss, and welcome!
I've got some clunking coming from the rear of my X5 too, symptoms point to bushes. I'll be investigating over the weekend, and will replace if so. Only had the car a month, but done over 2500 miles already...
I've had mine remapped, well worth it, but don't clog it too much as the old GM gearbox doesn't like too much torque
As for the rumble, could be a number of things as mentioned, but don't rule out the gearbox! Plenty of posts on here, the 5-speed has had a few issues over the years.

Cool, an interesting read there and some nice pics, I'd have mine in bits if I had a spare car and some free time!
