Re: 1999 150 Ball Joint Replacement---Camber Adjuster

Camber is easy, just a spirit level held vertically. I just get one reading, go for a drive, then get a different reading. When I get a chance, I'll resolve the differences.

As for toe in, it seems to drive pretty straight but the steering wheel seems to be a little to the right. The van doesn't pull and the wheel doesn't want to turn, it just seems to want to be a little to the right. I had to replace the steering box a year or so ago but I didn't notice this problem then.

Toe in is easy to measure until I tried it. If I did the trig. right, a toe in angle specification of 0.06 degrees +/- 0.25 degrees comes out to the back should be wider by 0.03 inches nominally with a range of -0.096 to +0.15 inches. (29 inch outside tire diameter) That's over a 70 inch or so tire spacing meaning I have to measure with an accuracy of 0.14%. Tough to do lying on your back and with some frame members in the way.

I messed around with a laser level taking a shot straight down the middle of the van from the middle of the frame in front to the middle of the differential. Made some under the van measurements but I could just feel too much slop in my readings.

Then I rigged up a piece of angle aluminum to make an extension that went across the rim and extended ahead of the van. I measured from the van center line to this extension at a point near the bumper and a point near the front end of the extension. Sort of a similar triangles deal. The numbers don't match the other method. I'll play with it some more when I get a chance. It would be nice if I could take it to a pro and see what he reads and compares to my readings.

Oh well, fun and games until I really need to drive any distance.

Thanks

Pete
