Supradk Posted October 22, 2014 Share Posted October 22, 2014 What kind of fails does it come up with if it's finish? I can feel vibration's and hear rumbling when I'm cruising around. If I push the throttle it disappear. If I slip the throttle and it's "engine brake" it's also disappear. When the supra is cold there's nothing and then when I have been driving for 10-15 min and it's warm it comes again. What do you think guys?

Fitz Posted October 22, 2014 Share Posted October 22, 2014 Easiest way to tell if the propshaft is gone, look under the car, if its not between the gearbox and the diff then its gone (sorry I couldn't be of help) Quote Link to comment Share on other sites More sharing options...

Chris Wilson Posted October 23, 2014 Share Posted October 23, 2014 Get the car up on a ramp. Take three bolts out of the rubber coupling to the differential flange. See if there's any free play in the centre or front joints by trying to rotate the back of the propshaft. Put the coupling back together again. Remove exhaust heat shield, remove the two bolts holding the centre bearing housing to the bodyshell, beware of the spacer washers between bracket and body shell location. Pull centre of propshaft down enough to spin the housing around the propshaft. it should spin easily and quietly. Further tests really need it off the car altogether. Your description does not shout "propshaft" to me. Quote Link to comment Share on other sites More sharing options...
Supradk Posted October 23, 2014 Author Share Posted October 23, 2014 Hi Chris. Thanks for the replay! When I fit my spec 3 clutch there were no washers under the main bearing? Is that normal? Any other idea what can cause the problem? Quote Link to comment Share on other sites More sharing options...
Chris Wilson Posted October 23, 2014 Share Posted October 23, 2014 Post a photo of the driven plate (s) of this clutch. Does it (they) have damper springs in the hub? If not it may well be exciting the geartrain into odd harmonics and it's something you will have to put up with. I am not familiar with this clutch.

Supradk Posted October 23, 2014 Author Share Posted October 23, 2014 Chassis number is jza800022205 Can't post the link right now yes it has springs around the centre Quote Link to comment Share on other sites More sharing options...
Chris Wilson Posted October 23, 2014 Share Posted October 23, 2014 OK, even with springs some are fitted with much stiffer springs that excite the gear train into making noise. If this happened as soon as this clutch was fitted i would guess you'll have to live with it. If it was OK for a while after fitting the clutch you need to look further.

Supradk Posted October 23, 2014 Author Share Posted October 23, 2014 At the beginning it was nice and no problems but after 1000km it starts? So I think the clutch is ok do I have distance washers in the support bearing? Quote Link to comment Share on other sites More sharing options...
Chris Wilson Posted October 23, 2014 Share Posted October 23, 2014 They normally have two washers about 5mm thick, but their absence won't be the cause of your noise. Hard to advise without experiencing it first hand (in person). Quote Link to comment Share on other sites More sharing options...
Supradk Posted October 23, 2014 Author Share Posted October 23, 2014 Yes I can imagine that mate when the sound and vibration comes it's like waves. It's not constant. Quote Link to comment Share on other sites More sharing options...
Chris Wilson Posted October 23, 2014 Share Posted October 23, 2014 You could drain the diff oil and see if there are any metal particles in it, but I would expect a failing diff bearing or crown wheel and pinion to be noisy all the time. Also check the gearbox rear mount isn't collapsing, or the engine mounts havce failed. the late type mounts are particularly troublesome, but don't usually make that much vibration or noise in my experience. Check exhaust hangers as well. The gearbox itself could have issues... Quote Link to comment Share on other sites More sharing options...
Supradk Posted October 26, 2014 Author Share Posted October 26, 2014 Update's Got the car lifted up yesterday to check if there were anything wrong. The 4mm thickness washers there should be between support bearing and chassis was sitting at the bolt. we put them in the right place. propshaft and support bearing was looking good and there were nothing wrong with them. it drives smother now but the noise and vibration is still there. so now I think its the clutch that a "talking" ? here is the link to it: http://www.garagewhifbitz.co.uk/toyota/supra/clutches-flywheels/spec-clutch-1562.html any other idea's chris? any of you guys that are driving with a noisy spec clutch? :-) Quote Link to comment Share on other sites More sharing options...
Chris Wilson Posted October 26, 2014 Share Posted October 26, 2014 From the clutch site: "High torque sprung hub and disc assembly ". Probably exciting the gear train, if nothing else seems wrong. Live with it an see what falls off! Quote Link to comment Share on other sites More sharing options...
