My journey continues. I’ve learned more about the steering and suspension on 744 than I care to admit. Subject matter expert??? Possibly or very close. One day when I’m done I’ll summarize everything I know so others can benefit. 

Most recently the subject is suspension bearings or better yet, drive axle and tax axle control arms which contain the rubber bearings. 

I ordered every suspension bearing under the bus. Eight for the steering axle control/A arms and eight for the rear. 

These are the steer axle bearing. They press into the upper and lower control arms then bolt to the coach frame. 
       


These pics are a small selection of my installation of the TAG Axle control arm replacement and Drive Axle. Each axle has four arms each. My bone pile has grown, I’m down to two control arms, drive axle uppers. 
                                                                   

ZF Part numbers for rubber bearings and complete control arm assemblies for the drive axle and tag axle.

The steering axle control arm bearings are all the same, eight total. A press is required to remove and reinstall the bearings. 

The drive axle control arms are different lengths upper and lower. The upper are the longer. 

The four tag axle control arms are the same length. 

0501.314.963 Rubber Bearing-Steer Axle Upper/Lower Control Arm (eight total).

0501.222.516 Tag Axle Control Arm Assembly 

0501.222.518 Drive Axle Control Arm Assembly  
0501.222.517 Drive Axle Control Arm Assembly

This is a sampling. Some day I’ll write up the details and provide all the ZF part numbers. 

Essentially I’m zero timing the suspension. 

Take care,
