Aluminum Rail Replacement on a 2004 and Newer 5 Series BMW

A 2004 BMW 5 Series BMW has been in an accident. The left rail has a golf ball size bend in it about 10 inches from the front end cap & the right rail is swayed out by 15 mm. Estimator A writes an estimate to pull the front end of the vehicle and repair both rails. Estimator B writes an estimate to pull the front end and replace the left rail.
Who is right? • Estimator A is only right • Estimator B is only right • Both Estimators are right • Both Estimators are wrong
The correct answer is D Both Estimators are wrong and the following presentation will explain why.
Replacement of the Aluminum Front End Parts on a 2004 and Newer BMW.
The 2004 BMW 5 Series is mixture of aluminum and steel. The front end from the firewall forward is aluminum with the passenger compartment and rear section constructed from steel. BMW has developed and offers a training program on the only recommended procedures for the replacement of the aluminum front end structural parts. BMW at this time recommends a Cellete Bench or Car-O-Liner bench fitted with a Car-O-Flex with a Car-O-Tronic.
There are 3 rules for repair of the 2004 & later 5 Series BMW and they must be followed to the letter.
1. There is no pulling on the front structure.
2. There is no heat including welding on the front structure.
3. Rules 1 & 2 must be followed to the letter.
Before any repairs on the front section are started, the earth straps need to be disconnected. The BMW training class teaches 4 repair procedures: • Rail Front Section • Upper Rail Front Section • Full Rail Section • Full Upper Rail Section
The following presentation will show some of unique aspects of the repair process & need for this specialized training before attempting any repairs.
