Front drive shaft hitting trans pan
Has anyone had this issue when re-installing your front drive shaft on a LS swap? I'm wondering if the transfer case has enough play to rock towards the passenger side a bit. Just the corner of the shaft is hitting the corner of the trans pan. It's a new drive shaft and seems a little beefier than the original one, but I wanna see if any of you have run into this and what you did to fix it. I know there are some threads on this subject, but since most were several years ago, just seeing if anyone has come up with new solutions.

Re: Front drive shaft hitting trans pan
It appears that your u-joint yoke is wider. If so, why? What series u-joints are those? 1310? 1330? 1350?

I've seen this before. I believe most who did the swap clearanced the pan.

That is a 1310 u-joint so like was mentioned earlier you will need to clearance the pan.

Re: Front drive shaft hitting trans pan
I'm not sure what series u-joint this is. The shaft is from Napa and is what they listed as a replacement. The diameter of my original yoke looked a little smaller overall than this one, but if it cleared the pan it would only be a fraction on an inch, which I could see potentially being a problem. When you guys are saying "clearance the pan" are you talking about shaving the corner of the pan off as much as possible?

Re: Front drive shaft hitting trans pan
You can clearance it the hillbilly way by whacking it with a hammer, or in my opinion, the more acceptable way by cutting the corner off and welding a patch.
Just make sure to get enough clearance for when you stuff the passenger front tire or it may hit the pan.
