I saw a truck for sale(ramcharger), it said it had converted a p203 into a free wheeling transfer case and installed locking hubs. How the hell do I go about doing this to my 203?
Mile Marker sells a conversion kit for this t-case. It consists of a geared ring which replaces the spider gears in your t-case. So it will require a tear down of your t-case and if you need a chain, now is a great time to replace it.
wouldnt this save alot of gas?
It has the potential to save some gas. Some here swear that they do not gain any increase in fuel economy, but I've seen small increases in fuel economy on a truck I used to own which I did this conversion. Even though you'll turn less drivetrain with a part time conversion, your t-case will still have the same amount of internal friction which is alittle high when you have an NP203
It depends on what you place worth on. The part time conversion should save you some gas, but at the cost of less traction in inclimate weather. It might be of higher value to have all weather traction especially if you live where it snows or rains alot.
how much should I expect to spend?
Unfortunately Dodge trucks tend to be more expensive to convert compared to Chebby and Furd trucks also using Dana axles and 203s. Not only do we need to convert the t-case but Dodge in their wisdom used crappy unit hub Dana axles which cannot accept lock out hubs. To get lock out hubs, you need to convert the unit hubs to regular hubs which accept lock outs, which adds to the expense.
what do i need?--plz help
A desire to do it
