SupraP-Z Posted February 4, 2012 Share Posted February 4, 2012 Been having a few issues with steering recently, the car has been pulling to the left, and pulling to the right...feels quite unbalanced when driving. I thought it may be the tracking so i took it to a garage and they said the sub frame is moving when i turn the wheels...could this be a case of loose subframe bolts? Do they just need tightening? or could it be something else... Quote Link to comment Share on other sites More sharing options...
mwilkinson Posted February 4, 2012 Share Posted February 4, 2012 They are known to need tightening every so often. Torque them up and then see how it all feels. Quote Link to comment Share on other sites More sharing options...
Ian C Posted February 4, 2012 Share Posted February 4, 2012 I have exactly the same issue at the moment. It's been 6 or 7 years since I got the bolts tightened and it's supposed to be done every 3 years or so according to the service schedule. I suddenly have tramlining and I know it's not the suspension or shocks, the alignment, the tyres or tyre pressures - they have all been done/replaced/checked recently. It is, however, going "clonk" when I reverse at full lock - classic subframe bolts. Do a quick search and you'll find the torque settings for the six or so bolts that need doing. They aren't too high, a normal decent torque wrench will do the trick, I just haven't bothered yet as it's cold outside and I'm not driving the Supra anyway Probably need a re-alignment afterwards though, unless I'm lucky... -Ian Quote Link to comment Share on other sites More sharing options...

Dnk Posted February 4, 2012 Share Posted February 4, 2012 It'll take longer to put the car on the ramp than to tighten the subframe bolts/nuts Quote Link to comment Share on other sites More sharing options...
Abz Posted February 4, 2012 Share Posted February 4, 2012 Good thread, better have mine checked when it up on the ramp. Quote Link to comment Share on other sites More sharing options...

Dim Sum Posted February 4, 2012 Share Posted February 4, 2012 This noise, will you only hear it when going above 30mph or could it be heard from any speed.? Quote Link to comment Share on other sites More sharing options...
Scooter Posted February 4, 2012 Share Posted February 4, 2012 I don't have a torque wrench otherwise I would do it myself Dunk. as Scott says you don't need one to check them out. I remember someone haing finger tight ones so them popping underneath and nipping them up is a start! you will need a deep 17mm and 19mm socket to get to the front ones though.

Dnk Posted February 5, 2012 Share Posted February 5, 2012 I don't have a torque wrench otherwise I would do it myself Dunk. I'd pop it to a local garage and put it on a ramp and do a bolt check front and rear. I did this on my car last year but i do have a very good local garage who i know very well and was happy to do this, cost me £30 I dont think guessing torque settings is the way to do it personally Quote Link to comment Share on other sites More sharing options...
Lude Posted February 5, 2012 Share Posted February 5, 2012 this applies to all cars, not just supras, and yes it is very annoying sound Quote Link to comment Share on other sites More sharing options...
Benjy Posted February 5, 2012 Share Posted February 5, 2012 (edited) Decent ratchet and FT calibrated arms should see you OK I like your style! My car does this too. Been driving me nuts!! Also, the nearside front wheel has slowly sunken further back in the arch, thus handling like crap in a straight line, and causing my wheel to foul the arch on lock over bumps! Irritating as it's smashed my wing up twice now. Edited February 5, 2012 by Benjy (see edit history) Quote Link to comment Share on other sites More sharing options...

Irritating as it's smashed my wing up twice now. Wow that seems a bit extreme. Is that solely down to the subframe needing a tighten? I would have thought there would be a lot of play in bushes to allow that sort of movement. I would always torque them up properly when you could but FT definitely works to get you by. I doubt you would manage to get the full torque on them with a wrench anyway, a breaker or a torque wrench would always be needed for the full leverage required. I would always choose a ' tightened as much as I can with a socket set subframe' over a loose and knocking one. Quote Link to comment Share on other sites More sharing options...
Benjy Posted February 5, 2012 Share Posted February 5, 2012 I have got 20's on mine so it's more noticeable. I also hit a fox at 60mph or so. So theoreticallly, if the subframe was a lil bit loose, foxy impact on the nearside may have pushed the subframe into a position that would move the lower arm into a more rearward direction, thus pushing said wheel back in the arch. So, if I loosen the subframe, manipulate the nearside into a more suitable position using possibly a copper/hyde persuasion stick, bit of locktite on the bolts and a few cracks with the old windy gun, I should be laughing, right?

Scott Posted February 5, 2012 Share Posted February 5, 2012 Sounds like a plan. I would go canny with the persuation though Quote Link to comment Share on other sites More sharing options...
James Posted February 5, 2012 Share Posted February 5, 2012 Any guide as to where all the bolts are? I have a feeling that I need to do this. Quote Link to comment Share on other sites More sharing options...
Benjy Posted February 5, 2012 Share Posted February 5, 2012 Ahhh I don't do gentle, if in doubt, give it a clout etc lol I shall have a butchers when I FINALLY take it to the garage to do the clutch that I still need to buy from Mr Wilson!

Graham1984 Posted February 5, 2012 Share Posted February 5, 2012 This noise has been peeing me off for a couple of weeks now. I wondered why my tracking suddenly just was off. Quote Link to comment Share on other sites More sharing options...
GTR Fever Posted February 6, 2012 Share Posted February 6, 2012 hmm...wonder if this is the cause of my annoying suspension noise as well...will definitely check it out!..my noise happens when driving around at slow speeds or when i slam on the brake..

GTR Fever Posted February 7, 2012 Share Posted February 7, 2012 hope not...sighh...lol...if it is though, should i go with poly bushings or OEM?? (sorry for the thread hijack btw) Quote Link to comment Share on other sites More sharing options...
GTR Fever Posted February 7, 2012 Share Posted February 7, 2012 oh one more thing, if it's worn bushings wouldn't it make some clunking noise when driving through bad roads?...cuz i get absolutely no noise through rough roads, only when stopping or turning hard corners at slow speeds..
