Yes, on top of the kingpin >2. I am unsure how the kingpin-steering nuckle assembly is secured to the >upper control arm. It is very clear it fits in a tapered hold in the >lower control arm. OMG what a strong assembly. the bolt holds eccentric washers, allowing adjustment of alignment. THe washers hold the upper control arm. >Fig 33 3/3 seems to show the head of the king pin does not engage the upper >control arm on top of the pin.

It makes sense once you start to take it apart. assembly is in reverse order, except with snug fitting parts. Just tear into it. I used a jack under the lower control arm to ease the LCA down after it has been loosened from the kingpin, a controlled release of the spring pressure. for assembly, i jacked up the LCA to seat the knuckle in the kingpin.. >Thanks > >Robert, enabler of ed > > Tom Hargrave <[EMAIL PROTECTED]> wrote > > To: <[EMAIL PROTECTED]>; <mercedes@okiebenz.com> > > Date: 10/13/2007 8:27:20 PM > > Subject: RE: RE: King pin installation > > > > OK, then look at the following three pictures. > > > > Picture1 is of the page that includes the specs.
