Cadillac rear sub frame

At home, it normally would take about 2-4 hours. Since it is rusted out, then you will probably have problems with the bolts at control arms and spindles. Rust can make things extremely difficult and necessitate the need for more part replacement. Did you get a new or used part? If used, then did you get arms and spindles?

unscrewing the rusted nuts and bolts might give u a tough time, so i would suggest u to take ur cadillac to a dealer. http://cadillacsts.net/
