Alignment on 4wd
Hi everyone happy holidays to all. I am recentury just got my 67 k-20 back on the road and brought it to the alignment shop. The store owner didn't have the specs for the alignment in his computer and asked if I had any specs on it. I do not and was wondering if anyone has walked into a similar situation or has a resolution to this problem.
Thanks, Andrew |

Re: Alignment on 4wd
There is no provision for resetting caster or camber on four-wheel drives. The only thing you can do is set the Toe-in. According the the GM Service Manual, total Toe-in should be 3/16".
I would also suggest you try to find an alignment shop with an old-timer that might have actually seen one of these trucks before. I would steer clear of the NTBs of the world. Hope this helps.

Re: Alignment on 4wd
If you don't have them the factory service manual and the driver's handbook (owner's manual) have a great deal of information in them on service and maintenance.
Both are avaliable as reprints and you can download digital working copies of the chassis service and chassis overhaul manual here. RTFM ... Read The Factory Manuals... download 'em here If you are going to be paying a computer jockey to learn how to align your truck you might as well do it yourself with a homemade toe gauge.

Re: Alignment on 4wd
caster is designed into 4WDs. small adjustments can be made by taper shims between the spring and axle. camber is designed into 4 WDs also, but small adjustments can be made by shimming between spindle and steering knuckle. chances are you don't need any thing but toe in unless you have worn parts or accident damage..toe in, around 3/16s give or take..

Re: Alignment on 4wd
I seem to recall some 67 K20s had D44 front diffs. Supposedly there are D44 camber adjustment shims available. As I recall, the manual for my 72 K10 w/ D44 mentioned this as well.

Re: Alignment on 4wd
A dana44 will only need caster/camber shims if the axle was assembled improperly at the factory (extremely rare) or damage has occurred causing something to bend (another rarity). I have never needed to use shims on any of the many 4wds I've owned since the '70s. It sseems I might have heard on one person needing shims somewhere in that time, or it was just when I learned that was a possibility if and when needed. I still have a shop do my 3/16" tor-in setting on the alignment machine to assure they are not only pigeon toed 3/16" but also pointed straight ahead when the adjustment is done to a beam

Re: Alignment on 4wd
Worn ball joints and tie rods are about the only thing that would normally change the front end geometry.

Re: Alignment on 4wd
I'll also add that if the caster or camber is way off for whatever reason, they make adjustable ball joints to correct that too. Lots of jeep guys use them to correct caster in the coil spring frontends to keep caster in them after they get lifted.
