I dropped my truck this weekend using the DJM 2.5/4 kit. Looks like everything is good, but I can't get a good view of the drivshaft because the gas tank is on one side and the muffler on the other. The only full view is from the rear of the truck and all I can tell is that it looks strait. I drove it this morning up to 65mph and felt no vibrations.

Is there a method used to check the drive line angle?

Thanks!

 

Maybe you could go get the oil changed and while you're there, ask them if you can look under the truck.

 

You should be fine. I have a 2/5 drop and I dont have any problems. Did you get an alignment yet? Mine was way off after my drop was installed. Got any pics of your truck?

 

I'm getting it aligned tomorrow. I'll post pics soon!

 

Shouldn't the angle improve if it is dropped?

 

Yes, but you still need to set a strait angle from the drive shaft to the rear end after taking the rear leafs off and installing a flip kit.

Couldn't figure out how to post an image, but here are a couple rough pics...

 

looks good, yah its called the pinion angle, and you check the angle of the driveshaft from the trans output, and the rear end input. Then use shims in the leafs to get the angle correct. Any competent body shop/ mech shop should be able to tell you what angle shims you need.

djm flip kits do not require shims they are adjustable

 

I left my truck to get an alignment this afternoon, and will get it back this evening. I asked the guy to take a look at the drive line angle since he has a lift and could probably get a better view. In addition I explained to him how to adjust the angle if need be. I also asked him to tack weld the nuts to the pivot bolts for the A-arms. Just hope he got the steering wheel stait!

I'll let ya'll know how it came out tomorrow.

 

Patman03SprCrw,
Thanks for those pics, that explains the issue clearly to me.

 

Bro good luck....... but if you need to tell this guy what he has to do i wouldnt feel very confident with him under my rig!!!!! but if he has done many in the past then GIT-R-DUN

 

I wasn't so much telling him what to do, but what I expected from him. Kind of like, "you don't get what you don't ask for". The shop was recommended by 4wheelparts, so he has plenty of experience working with dropped and lifted vehicles... In the past I've had trouble with alignment shops leaving my steering wheel crooked.

Picked her up yesterday and the shop did a great job! Steering wheel is strait and so is the alignment.
