Re: Project "Just an Old Truck"
Tonight I did a little post install rear end check. Topped off the fluid, and reinstalled the 3.5° shims Hart_Rod loaned me, I had a little vibe on the round trip to work today. Going to drive it again tomorrow, hopefully it will check good. Waiting to hear back from the guys at Porterbuilt about a trailing arm crossmember to fix the goofy wheel well issue. If I can get that settled the next big project will be the crossmember and forward arms.

Re: Project "Just an Old Truck"
What kind of vibe are you getting? Ever since the 700 install I get a very light vibe under hard acceleration. Just enough to notice.

Re: Project "Just an Old Truck"
At around 55-60 it is a mild vibration that you feel in the seat (does that make sense?) and between 60-65 it gets worse. It's not felt in the steering wheel, seems to be isolated to the rear. I had the shims in before the rear end swap and it seemed better, but I wanted to start fresh so I would know what eventually fixes it. I am hopeful that a PB adjustable trailing arm crossmember will do the trick! We'll see.
As for your your truck, I think it is tire shake from all those ponies your trying to put to the pavement! ![]()

Re: Project "Just an Old Truck"
Morning drive report... Well, installing the shims seems to have created a new vibration. This is actually a good thing because it gives me something to compare and contrast. The vibration I have been fighting may simply be in the wheel balancing, because it is more of a shudder in the whole truck that eminates from the rear. This new vibration is more of a buzz at 35 and 55. I guess I will remove the shims and see if the new vibration goes away. No matter what, vibration or no vibration, it was a great drive to the job today.

Re: Project "Just an Old Truck"
Have you put an angle finder on the trans and rearend?
Just wondering where you are at.

Re: Project "Just an Old Truck"
The trans was 5° down before I raised the tail shaft about an inch and the rear end was 0°. I am going to have to put it up on the set up blocks tonight and remeasure everything again to varify, if I were to estimate I would think the trans 4° down and the pinion is 3.5° up with the shims. Where I may get into trouble is if the pinion is higher than the transmission (from the ground) causing the angles at each universal joint to exceed the 4° limit.

Re: Project "Just an Old Truck"
Curious to see where you end up degree wise. I have never even messed with the angles of the trans or rear end and its super smooth until I get on it. Even then it's a very slight wiggle in the seat. Prob just leave it be.

Re: Project "Just an Old Truck"
If that is all you have I wouldn't sweat it. My problem is that I avoid driving my truck over 60 mph because the vibration worries me...

Re: Project "Just an Old Truck"
Checked my angles and here is what I found. The transmission is 3.5° down, the drive shaft angles up 1.5° toward the pinion, and the pinion is 3.5° up. The transmission output shaft is .500" (1/2") lower than the than the pinion. Total angle at the output shaft is 5° and the total angle at the pinion is 5°.
Based on what I have read there should be no more than 4° total angle at any universal, and the output shaft and pinion angle should be the same (or close). My total angles at each Universal are 1° over the limit, but my output and pinion angles are identical. Are the total angles my issue causing my vibration? ![]() Here are the pics I took, as well as a layout of the angles... Pic 1) Output Shaft 2) Drive Shaft 3) Pinion 4) Angles on paper (helps me visualize)

Re: Project "Just an Old Truck"
If you a re going to swap the trailing arms or trailing arm crossmember,... I would work on it then.
Fixing it now,... may change when you swap parts later.

Re: Project "Just an Old Truck"
Have you driven it much with the rally wheels on it?
I wonder if that would confirm "wheel balance" vs driveline. I know the shims created a new issue,... just wonder if you should try your rallys before you pull the shims?

Re: Project "Just an Old Truck"
I understand what you are saying... Pondering it.... Not sure the rally's will fit the rear with the long rear end.

Re: Project "Just an Old Truck"
Swapped out the "modified" proportioning valve for a CPP disc/disc unit, test drive in the morning.

Re: Project "Just an Old Truck"
Wow! The proportioning valve made a huge difference, $40 bucks well spent.
