| This
Dana 30 features an open knuckle design with 7 1/5"
ring gear. Although the same model axle has been used
for almost 25 years, they are not compatible. There
are numerous various in brakes, hubs, differential
orientation, wheel bolt pattern, and width.
A
strength of the YJ Dana 30 is its use of reverse cut
ring and pinion. The ring and pinion are stronger
when they are reverse cut in front axles. The reverse
cut axle also provides better ground clearance and
driveline angles.
Unfortunately,
the TJ does not use the reverse cut Dana 30. It uses
a normal cut Dana 30 similar, but not compatible to,
the CJ Dana 30.
The
YJ and the TJ Dana 30 uses the 5 on 4.5" wheel
bolt pattern. The YJ Dana 30 is of course set up for
leaf springs and the TJ Dana 30 is set up for coil
springs.
The
Comanche (MJ) and Cherokee (XJ) use a reverse cut
Dana 30 and the Grand Cherokee (ZJ) uses a normal
cut Dana 30. Like the YJ and the TJ, these axles use
a 5 on 4.5" wheel bolt pattern. All of these
trucks use coil springs up front.
The
Dana 30 front axle was used for a short time from
1971-1973 in Cherokees (SJ), Wagoneers (SJ), and J-Series
pickups. |
