Rear suspension

[yaris 2sz]

yarissedan, did you cut the bump stops when installed the springs?
if you did it, maybe it's from this.

by the way, i asked the tte.de about bump stops cutting and told me that i don't have to do this. i have the tte springs

I have not been on for a couple of days but every once in a while I have heard a noise from the rear after dips. I have a little bit different exhaust sets up than everyone else and I believe that the axle is very close to the exhaust. I noticed this when moving my axle up to the higher position I will take pics later this week

No havent touched the bump stops. I dont think theres bump stops really to cut in the rear its a different type of setup than in the front. Its spring and shock combo.

DIY anyone ???


First jack her up i put the mounts as far away as posable so i have lots of room to play


pull the wheels off


position jack so it is under swing arm and to get the bolt out you need to slightly tap the mount up to take the cross load off the bolt

this is the bolt you will be taking out only one of mine seamed to have lock tight so when putting them back i used locknut on both with some grease


so once the bolts are taken from both sides you can back prop one first and this is the fiddly part, if you have only one jack ... to get the holes to line up you need to keep the axel at the same hight as both sides if you don't you will fined it easy for one side and real hard for the other, so if you can use two people with two are you can just prop one side as high as you can the go back to the other and so on until the holes match up


as i was alone i had to back prop it took a little longer when moving the axel up i used the cares weight to move the axel with a jack (so i am not lifting the car) (loren)for the sake of others that putting a jack under the center of the beam axle is a bad idea. It can be bent in that manner.




You can see the thread is shaved for the first 5mm witch means if you are having problems getting the bolt in you can give it a little tap with a hammer


After putting it all back i took if for a test run down bluegum road and it was crazy it just cuts into corners at speed and i did not see a drop or lift in hight, But i did fine the rear a little more bouncy, other mods i have done are the trd springs and struts, sway bar, strut brace, tires and wheels and this has been the cheapest and i enjoyed it to good luck !!!

some other pics of my old mans car and mine

AND129, I think you know this by the fact that you mentioned being careful not to lift the car at this point, but it's worth mentioning for the sake of others that putting a jack under the center of the beam axle is a bad idea. It can be bent in that manner.

Neat that you were able to do this without pulling the shock bolts and removing the springs. Probably a toss-up as to which way is actually easier. (only two bolts to drop the shocks and it should make the whole process of fitting those pivot bolts a lot easier)

[AND189]

ok thanks as i did say the car was not lifted by the axel only its own weight and i didnt have to many problems i will note it thanks mate

I would highly reccomend removing the shock bolts. I tried to do this without doing so being lazy and it costed me 30 minutes of fighting with the bolt hole and cursing and after simply just removing the shock bolts and taking out the springs it was bolted in place a few minutes later. Because of the tension one side of the bushing will line up while the other will not. I was able to get one in without removing the bolts but required assistance of another person usinga pry bar to get the inner bushing lined up while i jammed in the bolt from the outer side.

as i said i had no problems simple unbolt jack up bolt on that is the way i did it but if you think your way is easy go for it ether way once its done it is off tap

ha ha as i said it is my dads new toy he seams to get a new one every year nice car though only problem it is full of computers and shit ... nice car but i would not get one :)

i didnt unbolt the springs or shocks either. i did one side and then the other with two separate jacks.

Hi five

I can not really comment about a change in toe or camber, seems like they couldn't go too far off given the amount the axel pivot will move. The real deal here is the roll center. A dynamic point that the rear suspension seems to move around. Moving a suspension pivot point like this definitely changes that roll center. That relates to anti squat and has a BFD effect on suspenstion action and overall handling. This change is really several in one shot. Toe, camber (in the rear this also is called anti-squat), and the roll center. Changing the roll center's height will also change the roll axis. This means it changes how the front suspension relates to overall handling. I know you all want learn more about suspension design. Read some books so that you can learn more about this stuff. An author Fred Puhn wrote How to Make Your Car Handle. Lots of good easy to understand info. Most bok stores have it.

I'll try it soon.

Any updates on interferences with this mod? It seems to correct the rear alignment after lowering.

I am going to be swapping in new shocks next week and can easily do this while everything is off.

I just learned to adjust my driving to prevent the clunking sound. I looked at my gas tank the other day theres some scratches on either side but cant say for sure that could have been from when i removed my upper tie bar brace.

[advocate]

I say paint the gas tank and look for new scratches after hearing the clunking sound
