MG21103 Dana 30/44 Front Axle Tube Seal Pair For Jeep Wrangler JK JKU 2007-2018, YJ 1987-1995, TJ 1997-2006, LJ 2004-2006, Cherokee (XJ) 1984-2001, Grand Cherokee (ZJ) 1993-2001 (2PCS Black)

I have the disconnect axle in my '90 MJ and ordered this, aware of the claim that it would not fit because the disconnect shaft is so much larger on the inboard end. But it can be made to work on the right side. I removed the grease zerk, the clip holding in the seal, and the seal. Then I 1) cut the seal so it could be installed after the shaft was in and 2) opened up the inside of the housing on the lathe sufficiently to fit over the larger shaft. I then installed the seal in the axle housing and reinstalled the axle through it now widened enough for the large inner end of the axle to pass through. Since the axle is the same small size on the outboard end, I now put the seal over the top of the axle and pressed it in carefully so the zerk hole lined up. I then installed the zerk fitting and the spring clip which holds the seal in place. I made it a point to have the slice I made in the seal upward. It might leak a little water if fully submerged briefly, but heavily greased, as it should be, I believe it is a nice solution. The only thing to remember is if the shaft needs to be pulled, you need to remove the zerk and the spring clip. first. The seal will pull out as you pull the axle! Cool!!

Very innovative design. Make sure to follow installation instructions or you can have a leak like I did.

These work for stock shafts but when I installed Revolution chromoly axles, they and much thicker and the seals will not fit. The seal flange is 1/2" thick and the gap with new axles is much less.

Cheap and fit perfectly

Works on my 2005 TJ Unlimited. Nice replacement!

El eje del diferencial dana 44 al ser más robusto en comparación al 30 no sirve como par de junta.Aún cuando aplique silicona entro muy forzado y no permite la completa entrada, se rebajo con lija y se pulió y cuando finalmente entró quedó muy preciso, lo cual no lo deje, ya que si lo dejo al momento de estar en el aire quedó muy duro de girar con l mano, al momento de bajar la rueda si giraba pero es odvio que iba a desgastarse ya que el eje hacia girar la junta completa, y esos migajas de aluminio pueden ser peor para el diferencial interno. Conclusión no sirve para Dana 44 ensamblado en Venezuela, otros diferenciales tal vez si

They're good at keeping bigger things out. Rocks, sand,mud. But I'm pretty sure this is what trashed my axle. If water gets in there, it traps it. No where for it to go. That's the only downside. Installation is easy. Put on rtv and pop it in.

I have been running these for around a year and they seem to be pretty resilient. They are simple and easy to install.

It helps to grind a notch in the axle housing right beside where the grease nipple sits on the seal in order to make putting a grease gun onto the nipple easier in the future. If you look at the pictures, you’ll see the area on the housing next to the nipple That I ground away a little bit .Please don’t contact me with questions. That’s all I have. It’s a good product and simple to install. If you have the ability to remove the axle you will easily be able to install these.If you are not mechanically inclined, have a shop

Put them in my dana 30 on a 04 tj no worries really happy with them thanks

👍

They only fit on the driver's side . Did not fit on the passengers side to small .
