WS6- squealing when turning slow
When I turn at slow speeds, I hear some kind squealing or "whirring" sound coming from the rear of my 2000 WS6. I have 4.10 gears so I'm thinking a mechanic messed something up when the last owner changed the gears.
Anyone have this problem before?

I had a groaning sound at low speeds when turning...changed the gear fluid (and added a TA Perf rear end cover) and voila, no more noise. Mine was a low pitched groan though. If it's a high-pitched squeal, you might want to have a different shop take a look.

I bought gear fluid. Did a Google search on how to change it but no luck.
is this something someone like me who only knows basic car knowledge could do? I know how to do an oil change, and change the tires... that's about it. where is the fluid reservoir anyways?

It's pretty easy. Drive the car a little to get the rear warmed up. Get the rear end up high enough to reach under. Use a 13 mm socket and loosen the bottom 3 bolts. Put a catch pan underneath. Remove the bottom 3 bolts and loosen the remaining 7, but make sure you leave at least the top one in. If the cover doesn't come off nicely, use a putty knife or scraper to gently pry the cover off and the fluid will come out. Remove the cover fully. Scrape away old gasket. Install new gasket with cover and tighten bolts. Fill with GM additive and gear oil of your choice. I used the GM gear oil specified in my user manual. I used 2 bottles of additive and almost 4 of the gear oil, but the TA girdle allows for more fluid. If you're completely stock, 1 additive and 3 gear oil should be enough.
Took me about an hour, and I'm no wrenching expert.

Does it have the factory posi unit still? If it is at low speeds and only when you turn it sounds like the clutches in the posi unit. You may just need to add some posi lube or possibly the unit itself is going bad. I would just check the level first and add a half tube of posi lube then see if it goes away...

Posi-traction unit to be more precise. It's inside your differential. The posi is responsible for making both wheels turn under power as opposed to just one wheel. Most posi's use clutches to "lock them up" when going straight and when turning, they slip a little so that the tires can follow two separate arcs without binding up. These posi's require special lube to operate properly and when the differential is low on fluid or there is no posi lube additive the clutches try to grab and produce a chatter while turning. You can buy posi lube at most parts stores...
