poly transfer case mounts, now case is \"knocking\"

Odd thing today. Recently (after tearing a rubber mount) I swapped all 3 mounts over to the poly style. Today while wheeling the transfer case started hammering the floorboards at time (mostly in sand) REALLY bad. It sounded/acted just like when I tore a rubber mount. We crawled under and checked all the mounts, tried tightening them up but everything seemed tight. Ther is a little play in the short arm mount it seems

Any ideas??

Bent transfer case arm? Mine did the same thing yesterday, landing hard after jumps at the dunes. Naturally, this happened on the first climb up the bowl. My mounts look okay, but the front u-joint hits the crossmember under hard acceleration. I temporarily fixed it with a walmart ratcheting tie down, pulling the t-case arm to the passenger side. Lame, but I diddn't have to go home.

Looks like a heavy duty arm and mounts are coming very soon.

Re: poly transfer case mounts, now case is \"knocking\"

Kind of stating the obvious but it souds like one of your mounting arms (prob the short arm) is bent or cracked.

It will be difficult to move the case by hand if everything else is tight but under exteme torque the vibe will show up.

I wheeled @ Zukimelt all weekend with a broken short arm mount (rubber). Noticed the vibration in the t-case shifter but not bad enought to stop wheeling. When I got home I was going to swapped in poly mounts anyway and found the short arm mound broked. Switched to the poly and no probs now. I'm running a mighty kong so mounts are beefed up well.

If u were runnig poly without beefed up mounts that's pretty hard on the stock mouting points. I've heard of problems with that.

I'll pull the short arm off and see what I see, may well be right. I may have even bent or cracked the "ear" that the mount bolts too.

They are homemade (not by me) beefed up mounts. That short arm definitely takes all the torque. Thats the mount I broke at Mason [img]images/graemlins/smile.gif[/img]

You really need a good short side arm to compare yours to. The funny 7 degee angle needs to be right so compare yours to a known good arm.
