Hello everyone and thanks for any and all help in advance!
I'm new to the forums, was brought here by watching the videos of a member (may03LT) after buying my well used, but decent condition, 2002 Trailblazer LS 4.2 I6 2x4 with just over 250k on the odometer. I originally bought it as a vehicle to drive while I work on my '98 Grand Prix. Well since I've had it I've had to replace the Oil Pressure Switch (IMO Stupid) due to the Gauge (fake) constantly going to 0, found out that the fan clutch is almost gone (think its original and surprised it's lasted) and now plan on replacing it, and now I believe the rear differential needs to have all its bearing replaced. The problem I'm having is identifying the diff I have to be able to order the parts from RockAuto.
What I have been able to find out so far is that I have a 3.73 Gear ratio and RPO code GT4 (GT4 Rear Axle (5X1) 3.73). What all that tells me is that I think I have a 8.62 ring gear and if that is correct I know what I need to order, however any additional input I could get would be greatly appreciated. I really don't want to order parts and find out I've gotten the incorrect master rebuild kit. This is the first time I'm going to be doing work on a differential.
Again thank you for any, and all input.
