By taper bearings do you mean taper rollers like a car wheel bearing?
Kind of, but I was thinking of the timken type used my lathe, little bit smaller I think.

not sure on the front wheel drive description for angular contact but if you google it you will find lots of advice from manufactures, the best way I cn think of to describe it is if imagine a normal bearing with the races opposite each other then on an angular contact bearing the bearing surface of the outer race is rotated through 45 degrees and when another one the mirror image of it is used it can resist radial and lateral loads. probably better to google it

Jeremys Spindle design is an excellent thread and I have all the parts to make one soon.
there are other good theads on here just search spindle( Bamboko's(?) 'small spindle' and Hilton Steves DIY spindle come to mind)

If you use a double row angular contact for the front bearing then the rear bearing can be almost anything is it is not taking any load. and should be able to float axially.

you also need a lathe to make most of these spindles, do you have one? I did see an easy to build version that used a piece of seamless steel tube and flanged bearings, preloaded by the spindle shaft, job done. if its for minimal use then just replace the cheap bearings on a regular basis
