i have a mk4astra 1600 8v 4 stud on an 02plate, during all this snow i cliped a curb buckling a rim and twisting a wishbone, not good. got wish bone changed by garage and they said they done trackin aparently. but i drove out and noticed a slight hum on right hand side wen turning so i bought wheel bearing, and also noticed steerin wheel not coming bak to centre but steering is not heavy.anyways thought i wood do wheel bearing myself..I have loosened everyything (tie rod end. castle nut.torx bolt.wishbone. and two bolts on shock strut i think its called )still cant remove drive shaft from gearbox am worried if i pull to hard it may come outa the gear box.shocked it with a bit of wood and a hammer but no go..sorry also its on front right side do i need speed sensor??as i took wheel off and old ones there in clip but not connected to anything so not sure if garage has left a loom out. any tips and hints will be greatly appreciated.
