Scooter Posted May 12, 2015 Share Posted May 12, 2015 sticking brake calipers? After market wheels without hub rings? Prop and or diff problems are rare, obviously not unheard of but rare. Quote Link to comment Share on other sites More sharing options...
chrispot Posted May 12, 2015 Share Posted May 12, 2015 as above, and could also possibly be wheel balance, deformed tyre, buckled wheel. don't think it would be, have you checked tyre pressures. you could jack up car, get some to run car to 55 mph whilst you check for all above? just make sure it's on axle stands both sides of the car! regards chris.

Guest AlanHutchinson Posted May 13, 2015 Share Posted May 13, 2015 thanks guys i will have a look just wanted to know if they are common for prop issues Does it get worse with engine speed or road speed? To check the prop, support it on axle stands out of gear and give it a twist. If there's play when you twist it, it's likely to be a universal joint. Try to wobble it up and down, if there's play there it's likely a prop bearing. I don't know supras too well but am familiar with this kind of drive train. As mentioned above check brakes aren't seized on? If they are j spec or na brakes you wanna check the sliding pins on the calipers, free them off and grease up accordingly.

K22SUP Posted May 13, 2015 Author Share Posted May 13, 2015 Thanks Allan there is a wee bit of moment up and down and in twist but what amount of movement should be allowed thanks edd Quote Link to comment Share on other sites More sharing options...
Nic Posted May 13, 2015 Share Posted May 13, 2015 (edited) Very difficult to diagnose on here, it could be one of any number of things, wheels, wheel bearing, tyres, brakes, transmission, suspension, etc. I would start by getting the tyres balanced, if that makes no difference then I'd get the car on a ramp and given a thorough going over underneath by an experience mechanic.

Guest AlanHutchinson Posted May 13, 2015 Share Posted May 13, 2015 Thanks Allan there is a wee bit of moment up and down and in twist but what amount of movement should be allowed thanks edd Is it free play or are you just taking up the slack in the diff when you twist? Check the flange on the front of the diff housing if you can see it. If it doesn't move as much as you are moving the prop then that could be your issue! Oh forgot to ask if it goes away when you come off the gas? Or is it just when you have the power on? Alan. Quote Link to comment Share on other sites More sharing options...
