Subject: Add-a-leafs? (Long)

Message:
Howdy,
I've come into a problem shortly after installing a rancho 3" lift on my
'97 Dak. It seems that the blocks on the rear axle are causing axle wrap.
When driving down the road I get a weird pulsation between 45-55. If I let
off the gas it goes away. If I get into the gas it goes away. It's just when
I'm cruising around that speed. It doesn't matter if I take o/d off or if I
switch to second and let the RMP's come up. At first I thought it was the
Torque converter not wanting to lock up (like it was hunting for a gear)
But, it's not that. It's like the rear axle is wrapping up or some sort of
harmonics, and once it starts the only way to stop it is to lift the gas or
speed up. So my question is has anyone had a problem like this? Could the
pinion angle be off? Would ditching the blocks for an add-a-leaf fix it?
Also do they make a 3" add-a-leaf and if so where do I find one? Any thought
or input on this would be appreciated.
Thanks,
HOP.

If you do go to the add-a-leafs its probably going to make your ride worse. I got the tuff country lift and I'm planning on taking the add-a-leaf out and installing longer blocks to bring back some of my factory ride. That doesn't sound right though. You might want to shoot an e-mail to BlueTwister and see if he's having similar problems with his lift (Rancho). From talking to him at the Dakota cruise-in at Lancaster, he said the ride was a little better than stock and that he wasn't having any problems whatsoever with the lift.

It does it @ 50mph. I thought that maybe a tire might be out of balance.. But, thats not it. Now i'm thinking that it has to be the torque converter. The only thing that baffels me it that it does it with OD on and off. As far as the ride it cruises great around town and @ 80+mph. Just at 50 the rear end starts to pulsate and hop around. Like if your mashing on and off the gas. Looks like i'll be looking into a tranny rebuild pretty soon. I've got over 117k on it and have driven it like i stole it since i drove it off the lot. -- Hop

Tx-Hop.. Add-a-Leaf would be about 1" then cut the blocks down 2".

I had this problem once after i did some hardcore mud stuff and it turns out that my tires were just way outta alignment so maybe you should have it aligned bc mine was doing that around the same speed and i got it aligned and it fixed the problem

I didn't think that they can do a rear end alignment. It feels like torque converter is going south. Or maybe the bushings on the leaf springs are weak.. i dunno
