Finally got the castor correction bushings installed and I need to have the truck aligned. Is there thing special with these trucks to align them? I've had my D2 for 17 years and never had an alignment even after dong a lift.
Nope. Center steering wheel and adjust drag link as needed. Then adjust track rod for proper toe.Is there thing special with these trucks
Somewhat common to change one thing, which effects everything else, and have a vibe show up.I’ve driven it about 30 mikes and have more low speed vibrations than before and some about 60 mph. It cost a fortune to get this bushings installed and had a hard time actually finding someone to do it. Just need to sort out the vibrations.
Yep, if it ever stops raining i'll get under it and check everything out. I did notice they had to replace a bolt and used one that's about 2 inches too long. That's just annoying.Somewhat common to change one thing, which effects everything else, and have a vibe show up.
One of the overlooked sources of issues when doing a change like this is worn u-joints in the driveshaft. They get used to running at one angle, then you change the angle and they don't like it. Doesn't always happen, but when you've exhausted the normal stuff, consider this.Yep, if it ever stops raining i'll get under it and check everything out.

My pinion angle was way of I could pull the plug on the diff and fluid would pour out. The bushings brought it down so I'm happy with that. The vibration I have is at 30mph. Pretty sure the one that's around 60 is in the rear its not bad neither is audible at most.Even in factory configuration, the front transfer case shaft and the front axle pinion are not aligned; a spring lift contributes to increased driveline angle, but at least the pinion remains pointed where it was, more or less towards the transfer case. A side effect of using castor correcting bushings - not "common," it is guaranteed - is that the axle pinion is pointed downward, farther from the transfer case. It is rather uncommon for this not to promote front driveline vibration.
That is on top of these bushings having much shorter lifespan than factory ones, and lack of off-the-shelf replacement availability.
You are happy that the bushings made your diff hold more oil? That's a noble goal.My pinion angle was way of I could pull the plug on the diff and fluid would pour out.

IM(v)HO, caster-correcting bushings are the worst way to reconcile lift, handling, and driveline vibrations. You will likely need a CV/double cardan front driveshaft in future.
Terra Firma HD springs, which supposedly are just 2". And that's all I have to go on because they actually lifted it anywhere from 2.5" to 3.5" at each corner with how bad the old springs were At least it sits level now.Bump steer - how much lift do you have? Over 3"? If so, you could benefit from an adjustable/longer Panhard rod. I did it in my D1, with barely noticeable effect. Stay away from open-faced heim joints.
That's what happened to mine. No issues with steering just my diff angel.Terra Firma HD springs, which supposedly are just 2". And that's all I have to go on because they actually lifted it anywhere from 2.5" to 3.5" at each corner with how bad the old springs were At least it sits level now.
Sounds like I should carry on with just getting the bushings back into shape and see how it goes.
I installed terrafirma springs on my 300tdi. It has a too heavy brush bar / bumper and the extra TDI weight up front. I was concerned it would sag over time up front. However, just the opposite has occurred after only 10,000 miles. It’s sagging in the back. I now understand why some people complain about terrafirma,Terra Firma HD springs, which supposedly are just 2".

Fortunately I haven't had that issue (yet). I almost welcome it because HD springs were a terrible choice. The ride quality is just awful.I installed terrafirma springs on my 300tdi.
