How hard of a job is it to take the transfer case out and replace the plastic mode fork, or HOW DO YOU COMPLETELY DISENGAGE TRANSFER CASE FULLY ON H3 HUMMER 2006 BECAUSE THEY WANT ME TO CHANGE A PART IN THE TRANSFER CASE THAT IS PLASTIC TO METAL AND CHARGING ME 800.00 IN LABOR I DON'T FOUR WHEEL AND IM GOOD WITH 2 WHEEL DRIVE.

 

It's an all time 4 wheel drive vehicle. The plastic mode fork is known to fail, Why it wasn't metal in the first place is beyond me. Sometimes it needs other parts besides the fork, Don't know until the case is opened up.
