2 issues - 1992 Chevy Lumina sedan

need to replace front passenger side wheel bearing. Any complications I should be aware of? Did this job many years ago on a Baretta. Drove
the car for another 4 years so I assume I did it right :)
also, when turn signal is engaged for too long (as when sitting at a light for a long time), smoke starts to wift (not waft) from the top of the steering column. Presumably there's an issue w/wiring therein. Is it necessary to pull the steering wheel? Although the car is in superb condition w/low mileage, I'm thinking of cutting or sawing the plastic shrouds and gaining access that way (after all the car is 17 years old). I can always glue or otherwise repair that, why pull a steering wheel, especially since I've never done it. Thoughts? Many thanks.

does the car have an airbag? if no, pulling the wheel is trivial with the right tool, and a steering wheel puller is not expensive.
