Swapped 10 bolt to 14 bolt 4wd malfunction?

Asked by Nov 13, 2015 at 02:49 PM about the 2003 Chevrolet Silverado 1500 LS Extended Cab 4WD

Question type: Maintenance & Repair

When I engage the 4wd the transfer case becomes hard to take out of gear and
the front wheels don't disengage. It is a 14 bolt hd rear end with the same gear
(373) as my previous 10 bolt rear end which also had (373).

If the gear ratio is the same there should be no issues with the transfer case. Double check the gear ratios! I think you have a problem with the transfer case that is un-related to the rear-end swap.

Even if the rear end is hd with ratchet lock? Cause of. Our service the gears are alot bigger in size.

If the gear ratios are the same it will not affect the transfer case no matter what type of locker you have. If the gear ratio is different then either the front will be plowing or the rear tires dragging. Try driving it a little in dirt and have a friend watch and see what is happening.
