bouncing and skipping yes! but this is only really noticable under 20kph. above that you wont notice it. When parking at shopping centres you will get alot of attention also. Not the best for a daily driver, but i would rather a locker than single spin any day. I would not run anything over a 205 tyre -> more grip = more strain on poor esky axles
Have you blown your current centre, or have you just snapped an axle? Do you get any forward movement when in gear? If you just snapped a twig, you can pull your centre out and weld up the spider gears, and stick another axle in it. If you have blown the centre you will no about it when you pull it out.
Either way your gona have to pull out the axles and centre. Just follow a haynes manual and its a piece of cake!
Tip: Stick some headbolts or metal plate into the spider gears before you weld it up for some strength.
