If you notice oil leaking from your swing axles or see cracks in your axle boots, it may be time to replace them. Follow along as we show you all the steps needed to replace your swing axle boots. Keep in mind that having your transmission out of the vehicle is not necessary to replace the boots although it makes it much easier.

Hello, Sam here with
JBugs.com. Now that our transmission is cleaned up a bit, we will prep it for
install with new swing axle boots to replace the torn ones before installing
the transmission back in our 1963 Resto Custom Beetle.
We start [by] removing
the old swing axle boot by removing both clamps and cutting along the seam to
avoid having to unbolt all the original hardware. The new boots come with
hardware so we aren't concerned with saving the old clamps, bolts, washers or
With the boot removed,
the axle tubes and flanges in the transmission are cleaned up and degreased
with some carburetor cleaner and wiped down with a clean rag. We will be
installing EMPI's deluxe swing axle boots. Since we have red shock absorbers
and a few red urethane components going on in the chassis below, we are going
to keep with the theme and install red boots.
A thin coat of RTV is
spread across the seam flange before the boot is spread open and placed on the
The bolts for the tube
are installed and hand tightened at either end to keep the seam together. The
remaining bolts are installed in the boot and all bolts but the ones nearest
the transmission are tightened down. We align the boot facing up and point them
backwards just a bit towards the rear of the car. The loose bolt at the
transmission side is temporarily removed so a bit of RTV can be squeezed into
the split at the boot and up into the seam. The bolt is threaded back into the
boot and tightened down.
The large end clamp is
placed around the boot and transmission flange and loosely secured. The boot is
squeezed together at the transmission and another set of hands can be helpful
so that the hose clamp can be tightened down while the boot is squeezed
together. At the small end of the boot, the clamp is loosely attached, the boot
is squeezed together and the hose clamp is tightened down temporarily. The installation
is the same for the opposite side and with the boots installed the transmission
can be installed back into the car.
The angle of the seams
at the axle tube will be clocked once the axles are attached to the spring
plates. That will be in our next video, until then set your browser to
