I recommended that you not do it yourself, actually.

Some people should do DIY repairs, others shouldn't. It isn't in any way a judgement on the individual. It depends on the training, mechanical aptitude, availability of a place to do the work, availability of tools, etc.

Posters that have all of those are already doing repairs themselves. Those that don't have those things shouldn't necessarily take a DIY approach. Especially if they have tried and caused themselves some problems. At the very least, they should consider getting a friend to DIY, and help them out by passing tools.

Many times people who ask on various boards about shop repairs get told to do it themselves. That is often wrong, IMO. There is nothing better for increased shop revenues than a DIYer who tried first and wasn't successful.

Just my $0.02
