Big Time shudder at low speed/low pedal

If it's about Power Wagons, this is where it'll go.

i use an impact hammer with chisel bit to turn the bolt head.
sounds like front shaft issue, i have seen many bad cardans.
must keep it lubed.

So I took another tranny guy for a ride and he really thinks it's the front drive shaft. Im in the process of pulling it but the. problem is one of the T40 bolts to the front axle flange is stripped....my luck isn't the best lately. Anyone have any ideas how to get it out? It was really on there tight before it stripped...I even heated it up with a torch and PB blaster!
Yep, torch and PB Blaster. Don’t fry the pinion seal! You can take the other bolts out and then remove the driveshaft, then that should expose what’s left of the bolt assuming it didn’t break at the bore. You can weld a nut on it or use an EZ Out.

I started a thread on DTX, I bought a big bag of Class 10.9 hex head bolts to replace those Torx fasteners from the front driveshaft because they break all the time. If you want a set PM me

Ugh! So I torched two bolt heads off and removed the front driveshaft...the symptoms are the same if not worse!! I rordered (and prepaid) new bolts already before I read your offer Damage- sorry. I would have gladly bought yours instead.

I truly hope this doesn't happen to anyone else, it's beyond frustrating....So I talked to the second tranny guy and he said that a converter shudder is not my problem, that occurs at higher speeds than where mine is happening.... I'm back to square one again I guess

I don’t make money off em. $6 I’ll ship you a set of hex heads so you don’t have to screw with torx bolts that shear off again.

Bummer! Might be time to pull the transfer case and check the input bearings. If your symptoms are same or worse with front shaft off, it might be right at the breaking point. Probably best to park it and figure it out. If you’re savvy you can probably drop the transfer case and trans yourself and at least dig around. You don’t need to build it yourself but if you separate the two you should be able to start seeing things like output shaft and bearings.
