All you need to worry about is getting the nut tight enough to hold everything in place but not tight enough that it changes the bearing preload. I have found that 150 foot pounds is about right. I usually use a new nut, but I always use red Locktite on the threads.
Be sure that you chech the pinioon bearings. It might be as simple as a loose pinion nut, but it could be a bad bearing. If it is a bad bearing then you have more work ahead of you.
