Offroad Trailblazers and Envoys

Intermediate shaft came out attached to disconnet assembly

G80, GU6, GT4, GT5, WTF? This section is for gearing and driveline stuff.

I was removing my broken 4wd disconnect assembly and the intermediate shaft that goes thru the oil pan came out attached to the disconnect. I tapped the end of the shaft and it came out of the disconnect assembly. I am not sure if the intermediate shaft is going back in all the way. I put everything back together, but the CV shaft will not go in all the way (it stays out about 1/2").

My fear is something fell off or is not aligned in the front differential now. Any chance something fell out of place? I removed the diff fill plug on the driver's side and everything looks ok, but I really can't see much.

Hoping for some help before I tear into the front differential.

How are you measuring your 1/2" out with the CV shaft? I haven't that apart but I've seen diagrams. It seems more likely the spring clip is resisting going into the diff would be more likely than anything to fall out of place.

The 1/2" I am talking about is the gap between the tripot housing and the seal face of the disconnect assy. There is visibly 1/2" of the cv shaft from the seal face to the disconnect. I didn't take a pic before I took it back apart.

I am hoping it is just the clip, any advice on how to push the tripot housing in harder or hit with a hammer without damaging the boot or the housing?

The new disconnect went on all the way, the cv shaft went in and I was able to connect the Upper control arm to the UBJ. That is when the tripot still has the 1/2" gap.

I put it all back together, here is the gap that I am refering to. I really hope it is just the clip, but I don't know a better way to push harder or hit the tripot to get it in all the way.

I just slid the disconnect with the cv shaft in it as pictured above away from the oil pan and the cv shaft did not go into the disconnect any further. I think this means it is not interfering with the intermediate shaft, I just need to get more midevil on getting past the c-clip.

Figured out how to safely hit on the tripot. Used a prybar to catch on the groove on the outside of the tripot housing, the sharp edge of the prybar catches the edge of the groove and a few good hits with a 2lb hammer got it home.

the tools.

Glad you figured it out.

What I do, is use the tripod joint as a slide hammer. I hold onto the actual shaft of the CV assembly, and ram it into the end of the tripod using it's slip-yolk functionality in my favor.

Also helps when you have the c clip facing upwards when you re install the shaft. Just future knowledge.

Do you mean the open part of the clip facing down?

Agreed Matt. What difference does the C clip orientation make Cody?

Cause the prying motion is up and the c clip would be facing up.. Making the cv easier to remove?
