Whether you're installing new drop spindles or have rebuilt your own, proper installation of spindles is a crucial step for driving safety. Follow along as we walk you through all the steps needed to be taken for proper link pin drop spindle installation.
Tools you will need:
2- 17mm Wrenches
Hello I'm Sam with JBugs.com. In our
last video we showed you how to rebuild your link pin spindles and with the
paint dry on our assemblies, we can now install them on our 1963 Resto Custom
At our front beam we clamp a framing
square to the flat edge of the lower control arm, so we can check the offset at
the upper control arm. With the square sitting next to the upper control arm,
we can see that we have a gap of 7mm. Checking a VW link pin shim chart for
1960 and later models, we can see that we use three shims between the spindle
carrier and the trailing arm on the upper and lower pins. The remaining five shims
will be installed on the outside of the pin before the pin goes through the
carrier. Eight shims must be used on each pin. The shims between the arm and
the spindle are used to accommodate the offset of the control arms. The other
shims are used as spacers for the length of the pin. 1959 and earlier cars will
need to reuse eight of the original shims as they use 10 shims per link pin.
Due to some damage on the carriers
near the link pin boxes, it's easier for us to install the shims onto the
carrier first at both the inner and outer, upper and lower positions. Then the
link pins are greased and slid through the spindle carrier. They're followed by
the O-ring seals, making sure that the O-rings are slid all the way past the
helical groove on the link pins all the way down to the shims. This will
prevent the O-rings from being pinched and splitting when the pins are pushed
through the carrier.
The grease caps are slid over the
pins noting that there is a notch and a dish in the cap that both sit towards
the trailing arms. Lift the assembly into place and slide the lower link pin
into the lower trailing arm. Push up on the lower trailing arm and slide the
upper link pin into the upper trailing arm. Make sure the grease caps are
aligned with the notches on the trailing arms. Push the entire assembly into
the trailing arms. Slide the lock bolts through the holes at the back edges of
the trailing arms. Rotating the link pin with a wrench may be necessary to get
the bolt to pass through the trailing arm. Install the lock washers and nuts on
the trailing arm lock down bolts and thread them down but do not tighten them
Rotate the link pin wrench one way
or the other and you'll see the pin move in and out of the spindle. Rotate the
pin so that it pulls in tightening the pin through the trailing arm. The pin
should be tightened to the point where there is no play in and out on the
spindle assembly but the spindle and control arms can still move up and down. With
the pin tightened, the lock bolt on the trailing arm can be tightened fully. Tighten
the other link pin using the same method.
The whole process is repeated on the
opposite side of the car where we had an offset of 6.5mm. So five shims are
installed on the back of the upper pin and three shims are used between the
carrier and the trailing arm. For the lower pin four shims are installed at the
back and four shims are used between the carrier and the trailing arm.
With the spindles installed a grease
gun is used at the upper and lower zerk fittings to lubricate the king and link
fittings. Pump the grease into the fittings until the grease seeps out of the
joints, and then wipe off the excess grease. With that done we're ready to
install the wide five disc brake rotors, calipers, and the remaining front
suspension and steering components which will all be covered in our next video.
