So today I had something happen. I changed out my clutch pedal. Took my 8 for a spin to get some food. On the way back I got into it a little. As i went through a stop light making a right had turn. I hit red line TCS was engaged as I hit the clutch. My 8 tried to keep going to the right and the steering didn't want to move. I finished my shift to second and still had trouble with the steering. It was not wanting to let me steer back to the left to straighten out . I gave it some gas and them it kinda popped. All was good again. When I got home I checked steering linkage it looks good. No acssesive movement. Any one know what it could have been?
Yah, DSC uses the ABS system (wheel speed sensors and brakes) to do its job. Could also be a problem with the ABS pump but a sticky caliper is a more likely point of failure.
Well I did not find anything wrong with the front brakes. The RR was a little sticky but not bad.
If it were the front brakes the steering wheel would continue to pull in the direction of the added friction. My case was not pulling it was sticking. I wonder if I have a issue with gears and contamination in the steering.
I would inspect the steering shaft's u-joint for for any tight spots and see if there is a lot of rust film around it. It may be that the u-joint was momentarily binding and is on its way out. Commonly when you see steering shaft failure you will have a hard spot when turning the wheel that will loosen as you turn the wheel more. The most common failure point is right on the rack as its the joint that's most exposed to the elements. Did the steering light illuminate at all during the momentary steering issue?
I can't tell you if the steering light came on. I was looking where I wanted to go and where my car was going. I'll look into it some more today. Will update with the problem when found. I have no problem checking out suggestions from you guys (ladies also).
If you turn the steering wheel in both directions all the way, are there any crunchy or otherwise unusual spots?
One thing that jumps out is that you were shifting at redline while going through a street turn. A lot of things happening there: your rear is loaded up, then you release the gas to shift, so the rear violently unloads creating oversteer (this is how Mustangs mow down crowds), all this in a turn so all the weight during the shift is on the front outside tire AND DSC responds to the rear wheels slipping by applying brakes on whatever wheels it thinks need to not spin any more (could be the rear or the front or both, it feels like sudden understeer). And then it goes into second gear creating yet another upset. You can try to recreate that scenario in a parking lot to see if it does the same thing, but it's not a good scenario to be in to begin with. I've done that in autocross when I first got the car, and while the steering wheel moved as normal, what the car did momentarily had nothing to do with where the steering was pointed.
Thanks loki. I will try and duplicate it. I am down to the steering column lock partially engaged and dsc acting up. It could have been the electric steering fighting me. I know I could not move the wheel till I shifted weight back to the rear. Every other time I have done that I have had the dsc/TCS long pressed off. Those times i had no issue. This ti.e i was just doing a quick test drive after the clutch pedal bracket instal. If it turns out the car was fighting me i may remove the electric part of the steering.
I don't think DSC would manipulate the steering itself, that's not part of the system. So there might be a mechanical problem in the rack, but I don't think removing the electrics would solve it.
If I wasn't trying to break my children from beating their heads on the wall.
I have not duplicated the issue. I really want to beat my head on a wall.
I figure I will just have to check steering linkage then run through the range of motion left to right and back. I think I'll do that with the front tires off the ground so I can get a better fill of the rack. I am procrastinating on the steering column lock. The pop I heard was similar to the lock engagement. Problem I should not be able to force my way past the column lock.
I love my 8 I have major plans for it. Pending the wife's approval of a budget. My children are mad they can't ride in "daddy's little race car" as they call it.
I do appreciate the help. This is the 8 in question. (If the photo posts)
Well I got it to duplicate the steering wheel locking. No matter what I did until I managed to have the rear end break loose it would not cause any issues with wheel movement. Once I got TCS to kick in (loose surface) then my wheel got stiff. Something popped In the front and then it was all good normal steering again.
Hmm. I'm going to have to go try that out. I drive on snow here and the TCS engages often, but have never felt anything in the steering wheel. Sounds like something in the rack is binding.
Yea. I am having to wait till I have some one to watch my children so I can get it up in the air. I am going to get info from alldata on the rack. I may have to make something at work to fix it or buy a new rack. Took me 8 years of please dear and a massive profit sharing to finally get the approval to buy a rotory powered car. Over all it's the most fun car I have ever had. My wife wants me to take it slow on modding everything. I want to get all rubber parts replaced and aluminum subframe bushings. Plan on getting a s2 transmission. If I can get a pettit sc come February then I'll be well on my journey to my dream 8. (Yes I have been through the major hp sticky) i have a few years till a track week with sim racing friends. Plan on hitting mid Ohio race way. Just have to tackle one thing at a time. Will update with what i find when i dig into my rack issue further. Or ask questions when they hit. Loki have a little fun for me on the snow. I'd love to go play some too.
Nice. What sim do you run? My rig is all apart for moving, but once I have a home again and it's winter, I hope to put in some Project CARS and Asseto Corsa time.
I was running pcars 2. Xbone. I also have run iracing but my children jacked the PC. My rig is perifrials are in a tote I am going to build another rig but for the time my 8 is taking away from me building a rig. I tend to drive more responsibly on the streets after a cop let me off easy back in 2004. I started in sim racing for the fact it is so much cheaper than real life.
Ok I have found the problem. A bolt for the ac compressor has worked loose and was catching in the u joint right above the rack. It was coincidental that it was duplicated only when I had dsc/TCS engage. Now it's the problem of getting to the bolt and getting it back in place or replacing it.
Yea I have pulled that tire off constantly. I think I know part of my love affair with my 8. Let's see how long I fight to do it the I can barely reach/see way before I give in and do it the know easy / fastest way. It has been 3.5 months since the last time I had the tire off. Thanks.
