its easy to do on your own.... but 200ish is a totally fair price to have it fixed for. a new axel will cost you around 100 and you need tranny fluid for aroudn 30bucks... so 70bucks for laybor isint bad, if u want to have somone do it for u.
15PSI - 30MPG - Megasquirt Tuned
when you do pull out the axle if you do it, please remember to drain your tranny fluid or else when you pull it out of the tranny you got tranny fluid all over you or the floor. also when you put fluid back into it after everything is done i suggest a 75w-90 mtf i have that and its smooth shifting
Actually your looking at close to $150 after you get an alingment done as well.
I say, replace the other axel too if it looks cracked or if grease is leaking out and replace your wheel bearing too. You can kill 3-4 birds with one stone. Trust me, 2-3 alingments a month is killing me.
