Driver's Side Sagging

Over the last few days I've been having a good fiddle with my suspension setup trying to get the car lower and balanced.

Basically what I've got are standard springs and Bilstein adjustable shocks. The spring seats were on the higher of the two circlip grooves, so I took the shocks out and moved the circlip down to lower the car that little bit. For my first time, it was a seriously annoying process. Eventually I got it all done.

I noticed then that the driver's side was sitting lower than the passenger side. I know that this sag does happen over the life of a car (and mine is 16 years old) so I thought what I'd do is switch the sides over to get it closer to balanced when my body weight is on the driver's side.

So I pulled all the shocks out, and made double triple sure that they were matching heights, and swapped them over.

Anyway, finished that and measured it up again and the driver's side is still sitting lower than the passenger side by about 10-15mm or so at the front (rears are almost identical).

What else can cause this sag? Worn bushes? Something else? Would love any help. Ideally I'd love to get the passenger side sitting down as low as the driver's, but if it's something that's worn then obviously that won't work.

I had the same problem mate. My drivers side was 10mm lower than the PS, so i just compensated by raising and lowering the circlips on the shocks. It now sits even.

I was told that cars of this age flex, sag, twist etc so its not that uncommon. Its unusual, however, that your rears are the same height and its only the front thats sagging. I actually had to work diagonally by raising the DS rear 1 groove and lowering the PS front 1 groove to get my desired height.

^^^ obviously :D

The difference is generally 3-4mm, park it on a road it'll look level, park on a flat peice of concrete it won't measure level.

Track springs are not the same...tracks have little to no camber, sports springs...some brands are some aren't.

Road springs.....

Left and right springs when new are generally a different height..it's to allow for the amount of camber built into roads, so the car can track correctly.

I've never heard of this before, i dont think thats true at all.

What car do you know came out with different driver+passenger side springs?

Does it sound like something I just made up? Or do you think it may well be something you have never heard about before?

Go search your vast bank of knowledge again, maybe you just missed it.

Answer to the question...all production cars have a bias, whether it's done via springs or other methods (it's so the car can track correctly on cambered roads-thats all roads) unless they have after market suspension.

I really am getting pissed dispensing sound advice, then having to explain it to the third degree.

I think I'll quit..

To the guy with the problem, springs will wear on one side of the car more than the other because it's under more load due to the camber built into roads. So if it's only a couple of mm it's normal.

I'm not questioning your theory, I just want to know what's causing it, as it isn't springs in my case. I explained in my first post that I have swapped the shocks and springs over but the drivers side is still sagging lower than the passenger side. My question is, what causes this as it cannot be the springs themselves.

      Recommendation for engine oil funnel spill free

      By MBS206 · Posted

      I thought I'd come back and add something I JUST learned. A Toyota LandCruiser with a 1HZ, mates perfectly with a bottle of Nulon brake fluid. As in, it perfectly screws in. Great make shift funnel when you cut the bottom of it off. This may work for your Corolla.   Unfortunately, tipping a 10L drum is much harder than a 4 to 6L bottle, and they no longer include the easy pour tap which was just perfection to use previously.

      Fuel Pump Control Module & Dropping Resistor

      By EndZee · Posted

      Guys since i bought r33 gts25t coupe 1994 automatic a/t(manual swap 350z gearbox)  all i got is problems, always problems. Lets start with that when i turn key into ignition(ON) fuel pump doesnt always works. Sometimes i have to turn key twice Off/on/off/on until it primes. Its new, dw300 - 340lph. My gearbox broke so i did gearbox swap, install different intake manifold, injectors and i take pipes. Car was sitting in garage for more than half a year. I did assembly all not that long ago and when i turn ignition cant hear prime. All of sudden it stopped working. Theres many videos on YouTube how to make relay mod on r33 straight from battery so i did and it doesnt work! 😰 30 - battery positive  87 - positive from fuel pump to relay 85, 86 - one of two wires from original fuel pump wires(light blue, grey) and it didn’t work. so I check on ignition and took original BLUE relays wires from trunk, next to fuses. (I believe it’s IGN+ and ECU pin 18. it didn’t work…  tried connecting (IGN+ from og relay) and (ECU 104 from 1of4 FPCM wires) to my new relay 85/86 and it didn’t work.  I unplug FPCM. Didn’t work. im thinking what’s wrong   fuel pump is working, if I leave IGN+ on 85 and 86 straight to ground it works but it’s just nonstop. Since it getting constant 12v after key in ON. light blue wire gives me 6-8v.  so how this should be connected? What causing ECU not giving — on pin? Or I did sth wrong and that’s why it doesn’t work? I need negative signal on ECU that control fuel pump. What this should be?

      M35 Brake caliper replacement

      By Duncan · Posted

      You can use your VIN to look up the factory part number somewhere like amayama, and then look to order new if necessary. https://www.amayama.com/en/genuine-catalogs/nissan Depending on price you might want to rebuild instead. @GTSBoy I had an interesting insight into US market parts when the Titan rear calipers were sticking. New calipers were dirt cheap, about 20% more than a rebuild kit....they are just considered throw away maintenance items

      Jacks that fit under GTR lips that can reach the subframe?

      By Duncan · Posted

      Lots of votes for driving onto a plank first; that is the quickest way I've found, 25mm is enough for my case but that will vary by car It also depends where you are going for. On the 32 I can get to the rear diff with my floor jack if I do that end first, and get it up on stands. Then I lift the front from either front tow hook as high as needed, also onto stands. Sometimes I need a small lift on the other tow hook to get it level enough If I do the front first I can't get to the rear diff because of the angle of the car Other options are getting to the front mount of the rear subframe from in front of the wheel (if only lifting one side, or just do both which is a bit of a pain compared to one lift from the diff), or also the gearbox cross member mount on the driver's side if you are  just trying to lift the driver's side. I This is the jack I use; it says 75mm clearance but of course that is only on the lower section so if you have to reach too far in like the diff you still get stuck. https://www.snapon-bluepoint.com.sg/category/Floor-Jacks/product/Floor-Jack,-2-Ton-Low-Profile
