oh damn. what the hell is a whatts link? so much to knowi looked under my car today and the diff looked to be perfectly level. so whats with that?
1: up towards the car? haha, in theory
2: yes i realised this after getting under my mates car yesterday, edited as such.
3: Mmmmm, watts link... would be nice but who can be bothered? (bar race teams yo)
Javal.
You can have any brew you want... as long as it's a Datsun / Corolla / What is that?

Ok, time to crack out MS Paint....
As you can imagine, lengthening or shortening the length of the upper and lower trailing arms (if you get an adjustable setup) will adjust the way the diff tilts (on all it's 3 axis, mind you, so measure them all against eachother). Traction brackets do the same, however they only effectively adjust the length of the lower trailing arms, and only adjust the tilt of the diff one one axis (forward / rearward roll, the one you want to adjust). The advantage of this is that you can have traction brackets in use with standard trailing arms. Disadvantage is that the adjustments are not as fine.
Also, supposing the rear end in your corona is the same as mine (i have an older model, xt130 bro) then you have a 5 link setup. 2 upper, 2 lower, 1 panhard rod. 5 links from rear end to body. but we're only worried about 4 of those 5 links at the moment.
EDIT: a watts link is like having 2 panhard rods. the panhard rod prevents the rear end from moving laterally, and goes from the mount on the body on one side of the car, to the mount on the diff on the other side. a watts link is pretty much 2 panhard rods, each mounting to the body at one end (one at each side) and then mount toward the centre of the rear axle. Sort of like a really wide V, but they don't meet in the middle(i think). advantage is it much more predictable and adjustable. (or this is how it was explained to me)

well what happens when the diff goes up and down when you got the watts link. wont the links just be pulling and pushing againsy eachother?
with the traction brackets do you need to remove the old mounts and weld on the new mounts?
you normally just bolt them on the lower trailing arm mounts
btw cool diagram javal.
Best that you guys a lot of research as to how suspension works.
Almost no-one in this thread has any idea what goes on.
Bill, why do you say that?
Here is a watts link, should be pretty obvious how it works. Fitting one to your sprinter would be pretty fabrication intensive. Would include making the link, mounting it to the diff and then getting suitable mounting points on the chassis.
the advantages are that roll centre remains more consistent (doesnt wander side to side or up and down as much as with a panhard rod). Also adjustable rear roll centre height can be built in if its for a racecar (like in a v8 supercar)
and then there is also a mumford that I think bill knows about
The "traction brackets" change how much of the acceleration forces generated are transfered through the trailing arm links (as opposed to the springs/dampers). The ones you can buy for your sprinter will make the car pitch rearward less (squat).
The replaceable trailing arms are for setting your diff pinion angle which AFAIK effects tramp. Also the allignment of the rear wheels.
I wouldn't claim to really understand suspension that well but I think Bill is right (it is a fairly complicated subject though)
ok ok....
