After driving for a few minutes a loud roar starts. I found that it was coming from the distributor when I put my hand on top of cap. Removed distrib. Gear looks fine, module not loose, blowed it out with air, just dust flew out. There is a metal cover over the resistor but its not touching anything. Turned shaft and noticed that after spinning a few turns it felt as if it was hanging on somthing just hair? Should I take apart and clean good?
For the shaft to stop turning it will be either a bent shaft binding up in the bushes---worn bushes or dry bushes. The feeling you are getting may be the points resistance as they are opened by the cam block. End float on the shaft is important as it will also affect the performance of the distributer.
SOURCE: loud roaring noise
jack up front of car get hold of tyre an see if u get any play if u do u may get away with nipping them up a bit
SOURCE: Makes a low roaring noise when you are at crusing speed.
One of the front wheel bearings are bad. Jack it up and see if one is loose, the noise will usually change if you swerve back and forth while driving. Could also be a rear pinion bearing in the rear axle.

This sounds like a noisy wheel bearing, they really can get loud, but quite when u turn because the weight comes off the wheel..
SOURCE: Loud roaring noise in front, steering wheel has vibration, replaced tires didn't help.
Wheel bearings are likly and I've changed many to solve this problem but it's esy to pick the wrong one with e vehical jacked and on jack stands suporting the car by the lower control arms ( normal ride hieght) run the car with a driver and listen to ti run , of course theres no load on the powertrain so there will be some lash ( power on to power decline ) cheack up. The roaring noise can be isolated by puting a sounding bar ( long metal rod ( sr=crew driver)) other against the part till the sound is rounded up rear but possible the carrier bearings in the (rear end) front drive. The axel bearings and on some units the carrier bearing thats in the CV axel on the block. Sounding rod will find and change the noisey part. Professional help is a good idea if you can't carry this out saftly
