Hi all, I have a random metallic knock noise every so often (maybe every 10 mins?) from somewhere near rear passenger side wheel. Often when gently accelerating in slow traffic. Had look underneath as suspected loose exhaust or suspension mount. Couldn't see anything there but rear diff has signs of oil leak on both side output shafts, and slight up and down play on shafts that gives metallic noise...
Guess the seals have gone and running dry, how hard to replace? Could there be further damage (speculative I know) or could replacing seals and re topping with oil solve (not sure if this is exactly the problem, but not good!).

Thanks for any advice!
