Front driveshaft upon lifting

[Rustyshackelford]

I asked the guys over at ORD about lifting the Blazers 4" and they sent this back about the front driveshaft.
"The front driveshaft has “stops” that limit the angle it can take, because at stock height they want the driveshaft to not be able to reach the ground in case a u-joint breaks. You can grind those out and then the front should work."


Has anyone had experience with this? Is it easy to grind?

I have never seen anyone tell me or read anywhere about grinding drive shaft stops.

Yes, very easy to do.
They are the square ended pieces that stick out.
Pull your frt shaft & see what I mean.
Grind the ends off & check for clearance.
There you go.

Yes I have done it with a 4 inch grinder. its easy. You need to do it on the 1008/1028 if you lift them 6 or more inches.

Sounds simple enough. Thanks guys.

 

[Rustyshackelford]

Two more questions.
1. Where are the stops?
2. Can you grind them with driveshaft installed?

 

[timarr]

You can see them when you rotate the shaft they will close to the cv joint. Yes you can cut in place.

I'm going to post three pictures with items circled in red. Please let me know which of these I am supposed to grind off.

that's a okish way to do it . but it also puts a lot of extra stress on the center piviot ball.

I ground mine to try it and its o.k. but not the best . and I didn't get that much more angle also .

You should not need to do this with a 4 inch lift. I have run 4 inch in many squarebodys both civvy and CUCV and never had an issue. In fact the front tends to sit a bit lower in diesel equipped trucks. My trucks have seen off road abuse and plowing as well.

I think you're right. I just came back inside from working on the truck and, at full droop with the new springs, the driveshaft turns smoothly with no binding.

I had no issue with a six inch lift.
