Look carefully,dont opt fot repairing left side axils ever specially inner gear side one though out left axil is also important,what actually they do(the machinists) they try to weld the the holes of the mesh in which the steel balls roll,because balls are of very hard metal they tend to get the mesh damage with the time and the holes in which they roll get loose,welded mesh will survive for few days and then again knocking.
The Left one is drive axil of any car,all the load is on left axil when pushing the car.so bro dont get into repair stuff.
