It's a coil spring rear. From previous experience with the welders around here, it's prob'ly gonna be a $2,000.00 welding job. Buncha thieves. I'll hafta try and find someone else. Where would I look in the archives for previous information ?? My main concern in welding on the rear axle is burning the oil inside the axle and winding up with chunks of carbon floating around. Is that a real concern ??
