Guest Chumpalot Posted July 19, 2007 Share Posted July 19, 2007 Me again After driving another member's Supra yesterday I found the steering to be so much lighter and even more responsive than in my car. In fact it was so light I managed to get the back end out for the first time (although it was a very minor) and felt confident I could control it. Got back in my supe and it was so heavy, felt like I was driving a car made in the 80s or something What could this be down to? Power steering pump perhaps? Low/no fluid? Tyre pressures? Thanks for any help. Dave Quote Link to comment Share on other sites More sharing options...

Dave 1st thing check your tyre pressures, when the pump starts going its usually a jerky movement when trying to steer Quote Link to comment Share on other sites More sharing options...
RobSheffield Posted July 19, 2007 Share Posted July 19, 2007 Same width front wheels and tyres on both cars? Quote Link to comment Share on other sites More sharing options...
Guest Chumpalot Posted July 19, 2007 Share Posted July 19, 2007 Cheers Rob, will check the pressures when I get in tonight. 36psi all round isn't it? 245mm fronts on mine, not sure about the other Supra. I'll check... Quote Link to comment Share on other sites More sharing options...
grahamc Posted July 19, 2007 Share Posted July 19, 2007 tyres pointing the right direction? Quote Link to comment Share on other sites More sharing options...
grahamc Posted July 19, 2007 Share Posted July 19, 2007 if no power steering fluid, it would make a funny noise... heard it yesterday, so unless you are completely deaf, you would know about it Quote Link to comment Share on other sites More sharing options...
Guest Chumpalot Posted July 19, 2007 Share Posted July 19, 2007 car was aligned and all the tracking and things were sorted out when I had the 19s put on Definitely can't hear any sort of noises, you mean when you actually turn the wheel right? Other tyres were 235mm in width. Quote Link to comment Share on other sites More sharing options...
hadyn Posted July 19, 2007 Share Posted July 19, 2007 Could it be your big heavy 19" rims mate? What size wheels were on the other supe? Quote Link to comment Share on other sites More sharing options...
Guest Chumpalot Posted July 19, 2007 Share Posted July 19, 2007 they were 17s before but to be honest the steering was quite heavy then as well. The steering on the other supe was unbelievably light and it actually felt like I had good control of the car. That one has 18" wheels on it.

RobSheffield Posted July 19, 2007 Share Posted July 19, 2007 Possibly try some new fluid in it and see if that helps at all. If MOT time is comeing up, and/or your car is high mileage it might be worth investing in some new ball joints and track rod ends and such.

bolarbag Posted July 19, 2007 Share Posted July 19, 2007 Who's car was it...and what mods did he have...could narrow it down a bit, but 19's will certainly affect steering as will running wider tyres But I would also like to know how to sharpen up steering...started a new thread, didnt wanna hijack yours incase you's a problem;) Quote Link to comment Share on other sites More sharing options...
Guest Chumpalot Posted July 19, 2007 Share Posted July 19, 2007 Thanks Rob, I'll try anything at the moment to be honest. Will check the pressures when I get in, going for 36 all round if it's not at that already and then will check the fluid. Only significant mod on the other car that would matter is the 18s (235mm fronts) and lowered (springs only). That's about it. I don't think the jump up to 19s would make the difference I felt in steering. It was so light. My car also isn't lowered at all although might be changing this soon with the aid of CW Cheers guys Quote Link to comment Share on other sites More sharing options...

Guest Chumpalot Posted July 19, 2007 Share Posted July 19, 2007 that rules the wheel size out then Quote Link to comment Share on other sites More sharing options...
RobSheffield Posted July 19, 2007 Share Posted July 19, 2007 What mileage on yours and the other? Quote Link to comment Share on other sites More sharing options...
Branners Posted July 19, 2007 Share Posted July 19, 2007 you may not be aware that the power steering is speed related. If your speedo conversion was done badly then it can cause the steering to be overly light at speed. You sure yours isnt normal and the other was light?

Guest Chumpalot Posted July 19, 2007 Share Posted July 19, 2007 What mileage on yours and the other? just hit 69k on mine. Other has done over 100k. Quote Link to comment Share on other sites More sharing options...

JB without driving another Supra I can't make that judement I'm afraid. Hopefully one of the nice chaps at the Grays meet will let me have a play around the car park on Saturday Quote Link to comment Share on other sites More sharing options...
bolarbag Posted July 19, 2007 Share Posted July 19, 2007 got heavy 19" on mine, and my steering is so light i first thought there is something wrong with it, like air, no resistence at all, very smooth. There will be something wrong with it, get it checked out, try sharp cornering around a track, the supra has got power steering but in comparison to new cars its like turning a truck Quote Link to comment Share on other sites More sharing options...
Guest Chumpalot Posted July 19, 2007 Share Posted July 19, 2007 that's what I'm thinking bolarbag. I'm pretty sure mine shouldn't be as heavy as it is, but not as light as the other supe. Somewhere in-between would be good. Checking tyre pressures tonight but I suspect these will be fine. Then going to check PAS fluid. Quote Link to comment Share on other sites More sharing options...
stevie_b Posted July 19, 2007 Share Posted July 19, 2007 As Branners said, how do they compare *at low speeds*, i.e. below 10mph? If his car is light at high speeds ( > 50mph) then chances are his speedo conversion is not the best. Quote Link to comment Share on other sites More sharing options...
Guest Chumpalot Posted July 19, 2007 Share Posted July 19, 2007 I've only tried these 2 supes so it's hard to know whether mine is heavy or whether the other one was light. At low speed I would say the steering in the other supe was still lighter than mine, then anything up to 110 leptons it was very light. Mine becomes heavy to the point where you feel you really have to hold on to stop the wheel from twitching around (which is not bad thing obviously) I'll see if i can get behind the wheel of some others and see what they're like Quote Link to comment Share on other sites More sharing options...

Mine becomes heavy to the point where you feel you really have to hold on to stop the wheel from twitching around (which is not bad thing obviously) Light steering at high speed is not good (IMO). At 70mph, you only had to look at my steering wheel and it would turn (before I got the Progressive Power Steering sorted out). When you're doing those sorts of speeds, it practically eliminates any feedback you get from the wheel. Surely it's the other way round: if it was light, you'd need to hang on tightly so that every piece of grit you run over wouldn't knock the wheels out of line. Heavy steering is more resistant to being knocked out of line. Quote Link to comment Share on other sites More sharing options...
Guest Chumpalot Posted July 20, 2007 Share Posted July 20, 2007 I get what you're saying Steve and I think you're right. My steering wheel seems to twitch a lot. Probably due to the larger wheels and the tramlining effect, I'm not sure. I can deal with this though. I didn't get a chance to check the tyre pressures when I got in last night and will do so tonight so I can eliminate that. Thanks for your help mate.
