Few Q's on my AU

[Cam]

Greetings,

In the next Few weeks my daily will be back on the road and the AU will come off. I need to address a few problems. For those of you who dont know I have a AUII GHIA (non IRS) with a 347 stroker

I'm Just after some advice..

1. My diff is making not nice noises, apart from whining, when i am turning sharply (and when reversing) i get a kind of "squeeking" noice, i cant really explain it much better then that, it kinda squeeks...stops...then squeeks again. As if its doing it at a certain point each time the wheels turn. As its a stock diff i am worried that it's possibly the axles, would this be the case? Also my LSD is dead and now only single spinning, would i be better off buying a full diff (XR8 non IRS?) and taking my gears (3.7's) and putting then into a new diff? Or rebuild the one i have?

Once again i have steering issues, previously i had issues with a knocking in the front end, turned out to be a loose sway bar. This time i have a similar knocking noise when turning hard into corners, it only seems to do it when turning left. What could this be? I also have issues with a virbrating when turning but i have been told thats just air in the lines.. correct?

My gearbox was rebuilt 10 000k's ago, but as its sitting behind a 347 stroker I dont trust it too much. Its stock with a 2900 high stall and big cooler, i would like to beef up the internals, what's it gonna set me back to get it beefed up with kevlar clutches etc?

I also have what seems to be a constant lifter tick, should i just take them out and inspect them? On top of this I have a knocking on startup, lasts about 25seconds, or until oil pressure builds, should i be at all worried?

And one more quick Q, is there any way of disabling the DTE warning beep on startup? With a stroker and around town economy of about 23L/100 when i am over a 1/4 of a tank it will still beep, lol. Any ideas?

Thanks in advance!
