Jim, that is high for those fluid changes. I had some PM done in July at an Isuzu dealer. The transfer case service was $35 labor and $3.98 parts. The front and rear diffys were $84 labor and $34.95 parts.
PM on any vehicle is not cheap with everyone charging at least $60/hour, but is has to be done. If you can't DIY, then you have to pay the big bucks. It's worth it to keep your VX running right. You can't ignore these things, it has to be done one way or another. At that time I shelled out $485 for a tranny flush, transfer case and diffy service, tire rotation, and front bearing repacks. I was happy to pay it. I've done almost all the recommended service along the way and after 4.5 years and over 90K miles my VX runs and performs like new. I've never been happier with my VX. If you want your VX to last you must be willing to pay for this stuff or DIY. There is no other option, period.
