    Does the Dana 44 use a strap type u-joint (one that uses a threaded u type bolt) and does the GM 10 bolt use a clamp type joint (with bolts that go through the strap) at the diff?

    I noticed that the 44 I have for swap also has the tie rod mounted on the top compared to the bottom mounted one on the GM 10 Bolt.

    I also see that the 44 and 10 differ in the mounting of the steering stabilzer. All these all common things for the 44?

    All the D44's and 10 bolts I have seen use bolts and straps. The yoke is threaded and the bolts thread into the yoke through a strap. 12 bolt chevy's use a u-bolt and nuts.

    My old D44 (w/ flat top knuckles...it wasen't the factory axle but I think it was still early 70's) had the u-bolt type

    My new D44 (3/4 ton from a 77) uses the strap type.

    They both used the same u-joint.

    Humm how did your tie rods mount? top or bottom

    This 44 has the strap that is threaded and passes through the yoke and is then held on by nuts.

    The old D44 had the tie-rod go in from the top and had a tube tie-rod and drop down TRE's.

    The 77 3/4-ton goes in from the bottom and has the L O N G solid TRE on one side and a short one on the other side.

    My 44 has the tie rod on the top.The drivers side is a fixed end and goes all the way to the pass side which has a small adjustable end.

    The D44 on my '73 uses the u-bolt style, tie rod on top w/ a dropped center. The 10B on my '80 uses the strap style, straight tie rod from below. Both use the same u-joint.

    I just removed the cover and here is the scope stamped on the ring gear. I would guess it was made in 12-9-72 but what do all the numers mean?

    12 9 72 DANA 18520 A3035 45-11

    The only #'s you really care about are the last 2.
    45 = # of teeth on the ring gear
    11 = # of teeth on the pinion

    45/11 = 4.09 which is your gear ratio.

    Can I use a 10 bolt tie rod on the top mounted 44? My 10 bolt has 2 removable ends but the steering stabilizer is mounted different. How would I rig up a steering stabilzer?

    You could use the 10B tierod on your D44 but might have to loosen the axle u-bolts to be able to get the TRE's in.

    Does anyone know of a clamp on stabilzer I could use with the 10 bolt tie rod since the mounting is different on the 44?
