I'd take your car to a different dealer, Obviously there is something wrong with your braking system.
Ok MR as it is you are faced with a HUGE problem.if the ABS lights on. it DEFINATELY means that the braking system detect something faulty you need to repair IMMEDIATELY.!!!another thing get rid of that DEALER he is BOGUS. if you value your life you will take the car back to that dealer ask for a replacement (ASAP) ABS light was put to report anything that's wrong with the braking.it's not there to just light up the dashit's a life death situation here you must take this matter more seriously.act early before it's to late pal.
You got serious problems - take the vehicle to a brake repair shop; but, be prepared to pay a high price Most shop get you in indicating they have specials and low prices on brake repairs. That is to get you in the shop. The law said that if a brake repair shop has your vehicle apart and find that you have a serious problem they can not legally put the car back together until the damage is repaired. Better to find someone who really knows about brakes and pay them to repair them in your back yard. Could be major repairs or something as easy as the sensor is unplugged or lose and a brake line is leaking and you need brake fluid. Brakes are funny things; could be real cheap or cost so much that it would be cheaper to junk the vehicle. Good luck!
Aftermarket remanufactured axles are avaiable at many auto parts stores. generally around $120 exchange. the labor to exhcange that axle and other worn out parts the technician finds while replacing that part. Good Luck
