driveshaft angles, what about horizontal angles

Hello, I noticed that in all the posts about driveshaft angles. The angle is in reference to ground or earth(using an angle meter which works from gravity)..My question is what about angles that might be there from an offset transmission(not where it should be due to improper mounting or maybe an accident. I do remember somebodys post talking about putting vehicle on a lift and laying on the floor and looking up at the driveline. Well, what is a good .......a straight driveline from tranny to pinion, or can there be offset? I raised a 1988 s-10 in the shop, got on the floor, and it seemed that there was an offset at the first section of driveshaft(between trans and carrier bearing). My guess is that there should be no no horizontal angles incurred along the whole length of driveline, but not sure

On a 1 piece driveshaft, the angle at the trans "U" joint should be the same as the angle at the rear "U" joint.

On your 2 piece with the hanger bearing, the same applies. You may have to adjust the hanger bearing down a bit to make the 2 halfs of the driveshaft as straight as possible.

if I understand your question,

drive line angles can be side to side or up and down. The shaft does not need to be straight from front to back on the horizontal

As mentioned it is best if the angles match at each end , no always possible though
Dont worry how old you are... it is the mileage on your body that adds up.

The centerline of the crank/trans mainshaft should be parallel to the centerline of the pinion shaft when looking from the side and/or the top. This will cause the angle of the u-joints to be the same at the trans and at the third member.

To add to what Frisco said. Off set pinion/motors is the same principal as the vertical angle (faces parallel to each other).
