Title: dana 30 axle seal tool?
Post by: mike s on March 23, 2010, 02:13:31 PM
Sigh going to have to tackle axle seals on my front diff, but i read they are a b#tch to do without special tool #*******, any idea who might have one? Also would consider spare front axle to build then swap complete....

they are easy.  screw driver to pry them out then large socket and hammer to tap new ones in.

Ya pretty sure it's inboard seals, i have the tube seals (like Dom) but have the two piece RH axle w/vacuum disconnect.

The inner seal should not be a problem, but you have to remove the vacuum actuator to access the passenger side seal.

I would recommend, using several 1/2 socket extensions snapped together (can get some really big one from p-auto dirt cheep) with a large socket on one end (can remember the size I used).  For the passenger side seal (assuming vac engaging model) you tap the seal into the engagement fork housing.

For the drivers side seal you tap the seal into the diff pumpkin. Installation is the reverse.  I would not push the thread rod technique its a pain in the butt!

Regards,

I have installed a couple of seals using a length of threaded rod, a plate the size of the seal and a plate for the outer end of the axle.
Put the seal in place slide the threaded rod through the axle and seal put the plate on the rod then a nut. Put a plate on the outer end of the rod with a nut and start tightening making sure the seal doesn't tip.
Long winded but I hope I explained it well enough.

tried this on a Dodge D44. it was a PITA.  it kept going in crooked;  one good whack on a socket and it set the seal much easier. 

the CAD one is beotch..........  if you're gonna pull that seal, might as well grab some one piece axles out of a tJ/XJ and put in the correct seal for this upgrade.................

I agree I installed the first seal for the disconnect axle and 2 months later upgraded axles and had to do it over again.

Which way would be easier or work best, the long threaded rod through the axle tube or the short threaded rod with washers within the pumpkin like in the link?  My understanding is there isn't enough room to get in there and get a straight hit with a hammer, thats why I was planning on doing it with the threaded rod.  This repair has been on my must do list for a while, I keep putting it off since I have never taken the guts out of the diff.  I hear if you mark it all well and keep track of your shims and where they go it is fairly simple.

JohnnyC's head can fit in the pumpkin, why not a hammer?

i use a 5 foot .75 dia rod  and a seal driver screwed on to the end and hit it in with a hammer. i also use the rod with a small littel scraper on the end to clean out the axel tube
also the rod is kept in my jeep to bash out broken axel  shafts from a  d35 if some one breaks an axel.

What I use is threaded rod and correctly sized drivers to pull the seal into it's bore , straight and without damage or the need for a swing press ( hammer)


I'm not aware of a commercially available tool to do this specific job  other than factory / dealership stuff  , that would be next to impossible to get.

A bit of creativity is required in this case and some problem solving skills.
