2+2 steering wheel wobble

Dave English <dandh....@gmail.com>: Aug 11 04:40AM -0700 Hi Mark.   You're right, you shouldn't be getting wheel wobble, although a tiny (and I do mean tiny) amount is possible on most cars because wheels are normally balanced off the hub. Getting the front wheels balanced should fix your steering wheel wobble.   As for the torque steer, most front wheel drive cars have a little but it's an acceleration thing, not really a fixed speed thing, so can I assume you mean that it's pulling to one side? As the car has been standing for a while it may be worth looking for a binding brake (or one not working properly on the other side), front or rear. In the past I have had front calipers binding. Even now, after replacing calipers and bearings, my front left has a little more rolling resistance than my front right, but it doesn't show on the road any more than any other car I've driven.   Can't really help with the tyre pressures as I run 185/60 R14 tyres on mine, but, if it's any help I have 25psi on the fronts and 20psi on the rears.   Hope this is of some use.   Regards Dave English Q2-009

Derek Clews <derek...@gmail.com>: Aug 11 01:11PM +0100 Hi Mark,   Got 2 Coupes and a 2+2 in the family garage , along with a Blackjack Avion 3 wheeler;-)   I had a similar thing on my coupe (finishing someone else’s project off) when I first got it fixed up and had to try multiple changes to make it get better.   If a car has been sitting around outside for a while the bearings can get water in them and rust will set in. That happened on my son’s coupe, had to replace some bearings when we first got it. Brakes will seize on or partly on and need to be freed off. Sometimes a disc can warp due to a partially seized brake calliper rubbing the pad on the disc as it drives, overheating it. Really an unused car needs more care than a used one and should be thoroughly checked when put back into service after a break off the road.   But start with the simple things. One of the wheel balance weights had fallen off mine so that helped when it was put right! Then logically check until you find the answer(s).   I found that my coupe was a bit of a saga. Brakes were sticking and a (not so!) obvious omission was there were no spigot rings fitted to the alloy wheels so they bolted up in slightly out of true positions and different each time! The drive shaft bearings where worn and I fitted refurbished driveshafts. All these things made it better each time, but not right until I checked the front hub runout with a dial gauge and found one was distorted which made the disc wobble - most noticeable when braking. It was replaced and I ended up fitting the discs back on using the gauge to get the best fit. It has been fine for years since.   I now try and make sure each car used used every month at least, winter and summer even though I am now doing very few miles a year.   On my 2+2 I run R14 but at 26 PSI front and rear seems to work OK. Good tyre wear patterns and handling.   Enjoy Quntum’ing. They are very engaging to drive and each have their own character.   Best of Luck   Derek
