When cold and pulling off in 1st gear there is a groan literally a groan
noise at pulling away speed from the drivers side wheel area. At least thats
where is sounds like its coming from.

Once the car is hot and been running for 10 odd minutes the noise goes away.
It only happens in 1st gear only pulling away or using first at all.

Any ideas what it could be ?
