Thread: Rear Thrust Angle Way Off

I gotta re do the alignment tomorrow cuz i think one machine is a little more accurate then the other. i threw it off the 2nd time i did it and now the steering wheel isn't straight. i think one machine is a little more accurate then the other. but it is going left.

and I don't think our cars have spindles in the back...

the part that the trailing arm bolts to?

Isn't that just the rear hub? And I'm gonna check those bushing tomorrow also to make sure there not rotted away. Doesn't seem like it would be cuz the under body is pretty damn clean.

The bushings I'm talking about are the two front ones in this picture. If one is worn more than the other, it can tweak the thrust angle. Also, if you have a collapsed spring on one side or coilovers adjusted wrong, it could twist the axle into a compromised thrust angle.

The hub is the part with the lug nuts on it. IIRC your car has a hub/bearing assembly that is held onto the spindle by a 32 mm nut. If your right rear took a good hit, it could bend the part that the hub assembly slides down onto and bolts to.

ok i see it now... someone from class said that lol i wasn't sure so i just said it on here lol

It makes sense that those bushing could mess it up, wasn't there some some aftermarket ones for it, Superpro or something like that?

So I re-did the Alignment and now the right side is fine and the left side is off I don't get it ? Maybe something on my rear end is loose? But I did use the good alignment machine today so maybe that was the problem.
Heres the readings for it.

Rear Left
Camber -.08
Toe .32

Rear Right
Camber -1.5
Toe .08

Total Toe .39
Thrust Angle .12

That dosn;t seem that bad but before the Thrust was .4-.7

And does anyone else with a sentra have camber bolts in the front? Some reason my sentra does and my 200sx didn't?

Also Checked the bushings out, they didn't seem that bad like I suspected. Do they make full prothane kits for front/rear on the b14s? I think I looked before and couldn't find them.

So your total toe went from 1.1 degrees to 0.39? Seems like either operator error or something as before your right toe was worst, now it's your left. Is it possible that you have bent wheels or loose wheel bearings?

They make ES bushings for the fronts of a B14 (same as B13) but I don't know about rear.

Something's strange...

i duno somethings messed up but the car is driving a lot better now

What Shigspeed said, also you could have tweeked the rear in a curbing incident.

Just saw page two, Are your rear wheels are bent and throwing your alignment readings off? I like to roll the car 180 degrees and remeasure. Do you get to spin the wheels before you take the reading to correct for runoff with your machine?
