Jo Neyskens Posted November 7, 2019 Report Share Posted November 7, 2019 My tr4 is lower on the driver's side. If I measure the distance from the ground to the chassis, it is the same height. The chassis is not damaged and has not had an accident. If you look at the car you can see it is lower on the driver's side. Almost 1.5 inches I think. In the meantime we have replaced the springs and the buses of the triangles but still standing lower. Can someone help me to fix this? The car is driving perfectly but it's a pity of the hight.

RobH Posted November 7, 2019 Report Share Posted November 7, 2019 (edited) If the chassis-to-ground clearance really is the same on both sides, it's nothing to do with suspension or wheels/tyres. Surely this can only be due to the dimensions of the body itself or how it is mounted on the chassis? Perhaps I have misunderstood what you are telling us.

You understood correctly :). One side of the body is indeed lower. I measured the chassis at various points but is is ok. Quote Link to post Share on other sites
Trevor Grant Posted November 7, 2019 Report Share Posted November 7, 2019 Hi Jo Someone at a classic meeting some years ago who had a similar problem on a 4A told me that they were going to fit slightly different length springs to the rear which they said should cure it, not sure if it did, just a thought.

Hi Trevor, thanks for the comment and help!! I think the measures of the body are correct. Maybe the body is not properly mounted on the chassis. More rubber on one side?

RobH Posted November 7, 2019 Report Share Posted November 7, 2019 Perhaps a combination of too high at the rear passenger side and too low at the front driver's side so the whole body is tilted? 1.5 inches sounds an awful lot though. Quote Link to post Share on other sites
John Morrison Posted November 7, 2019 Report Share Posted November 7, 2019 Hi Jo. 1 1/2 inches seems like a lot to me to be just body mounting, I would be looking at the mechanics. You say you have changed the springs, did you compare the old ones to each other and to the new ones? Are there the alumnium spacers on both sides ? Are the bottom wishbones mounted the correct way up? Some detailed photos are going to help here, but I wouldn't go pulling the body apart just yet. John. Quote Link to post Share on other sites

John - if the chassis sits level as Jo tells us, there's nothing wrong with the suspension. The suspension holds the chassis off the road, the chassis holds the body. If the chassis height is OK but the body height is wrong.........? Edited November 7, 2019 by RobH Quote Link to post Share on other sites
John Morrison Posted November 7, 2019 Report Share Posted November 7, 2019 Of course you are correct Rob, my thinking was 1 1/2 inches, and I can,t see that in body mounts. Thinking caps on? John. Quote Link to post Share on other sites

RobH Posted November 7, 2019 Report Share Posted November 7, 2019 Ah that's more believable. Maybe a combination of things? Slight differences in body panel dimensions plus how it sits on the chassis? Such things do happen. Quote Link to post Share on other sites
Jo Neyskens Posted November 7, 2019 Author Report Share Posted November 7, 2019 (edited) You only see it when you are in front of behind (little bit) the car. Edited November 7, 2019 by Jo Neyskens Quote Link to post Share on other sites

RobH Posted November 7, 2019 Report Share Posted November 7, 2019 As with all the other suspension components, a problem with the shock absorbers would affect chassis height Jo. Quote Link to post Share on other sites

Ah ok, thanks for the info. Then it's probably going to be the attachment body to the chassis? Quote Link to post Share on other sites
RobH Posted November 7, 2019 Report Share Posted November 7, 2019 (edited) Probably Jo unless someone has another suggestion. 15mm doesn't sound much and I think that personally I would just live with it as a quirk of the car. After all, production methods in the early '60s were not as precise as they are now. Looks a 'cracker' in the photo. Edited November 7, 2019 by RobH Quote Link to post Share on other sites

Malbaby Posted November 7, 2019 Report Share Posted November 7, 2019 Very unlikely to be body to chassis mounts. When you say you measured ground to chassis distance, was that front and rear? Quote Link to post Share on other sites
MilesA Posted November 8, 2019 Report Share Posted November 8, 2019 (edited) I am sure this will only confuse matters. A few years ago, my 3A started to sit lower on the driver's side - clearly visible from the front and by the different gaps between the top of the wheels and bottom of the wheel arches. Put it down to the oft reported driver's side sag. So had new rear springs installed. On doing so me spanner men discovered that someone had put a shorter hanger on at some time in the past no doubt to compensate for one of the springs sagging. Worth a look.
