it depends on what kind of car it is,you really didn't say,and on most vehicle made now you would have to pull the engine out to do this,and that could be very expensive to do,especially at a dealer,i really cant say what a dealer would charge for this,if i was doing it on a 4 cylinder engine it would cost around 600 bucks ,that's just to start with,and it may need more than that once they get in to it,its all going to depend on what kind of a car it is and how hard it is to do,good luck on it though,i hope this helps.

It depends on the car and the motor. And you never replace the (crankshaft) Main Bearings without replacing the (connecting) Rod bearings.
Properly, the motor should be removed which in some cases is eight hours labor times what ever they charge for an hour of work.
The actual cost of the parts is less than $100 for most cars.
The ideolgy for pulling the motor out of the car or truck is access. It's insane trying to pull off an oil pan, some vehicles you cannot, and work with oil dripping on your face for God knows how many hours. And, a properly installed crankshaft seal should always be done with the motor out of the car.
By the time most cars get the point where the main and rod bearings need to be replaced there is significant wear on the cylinder walls and piston rings as well. And the oil pump might as well be replaced if you are going to all of this trouble.
Best fix? Replace the entire motor and you'll have all new bearings and seals and gaskets and oil pump and rings and pistons and be ready for another 200,000 miles if you keep your foot out of it.
Good Luck!

You have to really love your car to do the main bearing fix. It is not just a matter of replacing the bearing shells. You will probably have the crankshaft reground too. As long as you are that far into it do the rings in the pistons, and a valve job, and why stop there? Once you get started you will find that the labor involved is not that much more to do it right, and the parts are the cheapest aspect of the job.
Or get a crate engine. Easy, guaranteed and much less labor.

It means rebuilding the entire engine..... but something sounds fishy. If you have less than 250,000 miles on an american engine and have changed the oil regularly, your bearings should be just fine. Bearings wear only after many 100's of thousand miles, unless the oil has been contaminated or run out, or for some other reason the oil pressure has failed. If so.... better fix the cause of the problem before rebuilding the engine, or you're wasting your money.

It all depends on the make and model of the vehicle, what I do is call a few different automotive places "ex. Auto Zone or Advanced Auto) and get a price for your make/model, then most dealerships have about a $50 an hour labor charge, that will give you a start, or you could call around some other mechanic shops and get a quote from them.
