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.

      Surely somebody has one in VIC. Have you asked at any shops?  Is this the yearly inspection or did you get a canary?

      Duncan's V37.......race car?

      By PranK · Posted

      This is where I share pain with you, @Duncan. The move to change so many cooling system pieces to plastic is a killer! Plastic end tanks and a few plastic hose flanges on my car's fail after so little time.  Curious about the need for a bigger rad, is that just for long sessions in the summer or because the car generally needs more cooling?

      So, that is it! It is a pretty expensive process with the ATF costing 50-100 per 5 litres, and a mechanic will probably charge plenty because they don't want to do it. Still, considering how dirty my fluid was at 120,000klm I think it would be worth doing more like every 80,000 to keep the trans happy, they are very expensive to replace. The job is not that hard if you have the specialist tools so you can save a bit of money and do it yourself!

      OK, onto filling. So I don't really have any pics, but will describe the process as best I can. The USDM workshop manual also covers it from TM-285 onwards. First, make sure the drain plug (17mm) is snug. Not too tight yet because it is coming off again. Note it does have a copper washer that you could replace or anneal (heat up with a blow torch) to seal nicely. Remove the fill plug, which has an inhex (I think it was 6mm but didn't check). Then, screw in the fill fitting, making sure it has a suitable o-ring (mine came without but I think it is meant to be supplied). It is important that you only screw it in hand tight. I didn't get a good pic of it, but the fill plug leads to a tube about 70mm long inside the transmission. This sets the factory level for fluid in the trans (above the join line for the pan!) and will take about 3l to fill. You then need to connect your fluid pump to the fitting via a hose, and pump in whatever amount of fluid you removed (maybe 3 litres, in my case 7 litres). If you put in more than 3l, it will spill out when you remove the fitting, so do quickly and with a drain pan underneath. Once you have pumped in the required amount of clean ATF, you start the engine and run it for 3 minutes to let the fluid circulate. Don't run it longer and if possible check the fluid temp is under 40oC (Ecutek shows Auto Trans Fluid temp now, or you could use an infrared temp gun on the bottom of the pan). The manual stresses the bit about fluid temperature because it expands when hot an might result in an underfil. So from here, the factory manual says to do the "spill and fill" again, and I did. That is, put an oil pan under the drain plug and undo it with a 17mm spanner, then watch your expensive fluid fall back out again, you should get about 3 litres.  Then, put the drain plug back in, pump 3 litres back in through the fill plug with the fitting and pump, disconnect the fill fitting and replace the fill plug, start the car and run for another 3 minutes (making sure the temp is still under 40oC). The manual then asks for a 3rd "spill and fill" just like above. I also did that and so had put 13l in by now.  This time they want you to keep the engine running and run the transmission through R and D (I hope the wheels are still off the ground!) for a while, and allow the trans temp to get to 40oC, then engine off. Finally, back under the car and undo the fill plug to let the overfill drain out; it will stop running when fluid is at the top of the levelling tube. According to the factory, that is job done! Post that, I reconnected the fill fitting and pumped in an extra 0.5l. AMS says 1.5l overfill is safe, but I started with less to see how it goes, I will add another 1.0 litres later if I'm still not happy with the hot shifts.

      OK, so regardless of whether you did Step 1 - Spill Step 2 - Trans pan removal Step 3 - TCM removal we are on to the clean and refill. First, have a good look at the oil pan. While you might see dirty oil and some carbony build up (I did), what you don't want to see is any metal particles on the magnets, or sparkles in the oil (thankfully not). Give it all a good clean, particularly the magnets, and put the new gasket on if you have one (or, just cross your fingers) Replacement of the Valve body (if you removed it) is the "reverse of assembly". Thread the electrical socket back up through the trans case, hold the valve body up and put in the bolts you removed, with the correct lengths in the correct locations Torque for the bolts in 8Nm only so I hope you have that torque wrench handy (it feels really loose). Plug the output speed sensor back in and clip the wiring into the 2 clips, replace the spring clip on the TCM socket and plug it back into the car loom. For the pan, the workshop manual states the following order: Again, the torque is 8Nm only.
