it entirely depends on what type of vehicle it is, what type of transmission is in it, the age of the vehicle and if the rear main seal is part of the oil pan gasket. Impossible to answer without vehicle informations.
How much does it cost to replace a cv joint on 4 wheel drive
To pay someone to do this job would not be cost effective. Better to buy a rear wheel drive vehicle and sell the front wheel drive vehicle.
pretty much you dont convert front wheel drive to rear wheel drive it would involve new engine, new transmission, new differential, new drive shaft etc just cost prohibitve and you would have to change suspension and a lot of engineering would be required just buy a rear wheel drive vehicle
Anything is possible with time, money and some serious modification. Front wheel drive vehicles are not designed to accept the dimensions of the parts that are needed for rear wheel drive. The engine compartment is designed to accept transverse (sideways) mounted engines not inline engines, there's no transmission and driveshaft tunnel, a custom driveshaft would likely be required, there's no clearance for a rear differential, etc. Converting a front wheel drive vehicle to rear wheel drive would probably cost considerably more than buying a rear wheel drive vehicle.
The short answer is - You Don't..... Seriously it will cost more to do this than it would to just buy a 2WD model.
That depends on the vehicle; you listed in far too many categories to have this researched for you. For many vehicles, especially front wheel drive vehicles, the front wheel bearings are part of an assembly and you will need to replace the entire assembly AND have the vehicle aligned when you're done. That runs up the price. For some vehicles, such as a 2 wheel drive Silverado, the wheel bearing just slips out when you pull the front hub. You DO need to work a little to remove the inner "race", but that's not too much difficulty. The whole job shouldn't be more than $40 or $50 for a 2 wheel drive pickup, but front wheel drive vehicles and 4 wheel drive pickups can be several hundred dollars.
There are several disadvantages to having a four wheel drive such as increased tire wear, lower gas mileage and an increased cost for maintenance of the vehicle.
Replacing one side halfshaft could range between $300 to $400.
You'd have to tell us exact year and model. Most American front wheel bearings cost anywhere between 35 -50 to buy and in a front wheel drive can take up to 3 hours to replace. In unpowered front wheel, usually about an hour.
It can cost between $80 and $200 to replace a drive shaft on this vehicle. It will depend on what a shop charges on the part and the labor.
you can't replace just the front wheel bearings, they are sealed so you have to replace the entire hub assemble and it will cost approximately $130 each side.
