Self repair for broken autofocus on Nikon F55

I have recently inherrited a Nikon F55 with a Nikor 28-100mm lens which came with the camera when new.

The lens has worked well enough in the past (it is my Dad's camera, and I remember it working when it was new), but now the autofocus is more of a hinderance than a help.

When I trigger the autofocus, 9 times out of 10 it will fail to focus on the subject. Sometimes it will pick another subject arbitrarily, and others it will just whir several times and not focus on anything in particular.

With the AF switched off, the lens will manually focus fine.

From what I can gather, this body had a common fault which seems to be what I'm experiencing, and Nikon offered a warrenty repair on it beyond the standard warrenty period.

As the camera is now the best part of 16 years old, I would be surprised if Nikon would still honour the repair, so I'm looking into whether this could be repaird myself.

I'm trying to source another AF lens for the camera to narrow the issue down to body or lens, but if anybody has any possible diagnostic steps I might take to help identify a likely cause in the mean time it would be appreciated.

I'm not inclined to have th ebody professionally repaird as they are selling for very little second hand, so its really a case of determining whtherI can fix it myself, or whether I should just keep it as a manual SLR.

I'm competant with electronics and very small mechanical devices, but not knowing exactly what's involved in such a repair, its difficult to decide whether it's worth it.
