It helps a lot to substitute the shock absorber with the threaded tool, then adjust its length to what you did when you had fitted the torsion bar - or to factory setting if you haven't removed the bars. Suspension arm bushes try to push the arm towards the half laden posiion and this puts some...

No, stud PCD is different.

A 1976 R4 visited my workshop today, and I thought to compare its chassis number with another '76 car I have in the workshop. Diamond plates are only 8 numbers apart! However, oval plates differ by 207 numbers, with the white car having the smaller number: Food for thought and discussion...

When suspension is compressed, camber becomes more negative and vice versa. I suppose you are checking camber at each wheel when it's parallel to chassis side member. With such a high caster angle, slight toe in / out alters camber significantly. If you have to check camber now before the body...

The camber angles can be corrected by putting shims between the suspension uprights and the chassis, at the top or bottom bolts. But first of all the car must be at the correct ride height, equal on both sides.

There is no metal-to-metal contact or sliding on these bushes. Not even rubber to metal sliding, because they are "flexibloc" bushes, this means outer sleeve vulcanised to rubber bush that is vulcanised to inner sleeve. Movement is achieved by the rubber part flexing. That's why it's important...

The lower edge of the "love handle" is fitted on the outer bumper mounting bolt by an "L" shaped bracket. Fit and adjust the bumper, fabricate the brackets (easy) and fit the handles. Adjust them so that the whole pressed section is inside the wing-bonnet gap, just as on your photo. Then open...

480mm for drum brakes, 405mm for disc brakes.

Worn arm bushes give sounds that range from creaking to clonking according to my experiece. Inner ones are the most suspect for noises as you can't see what's going on with them. Outer ones will usually first visually fail, then audibly. Don't overlook both shock absorber fixings, as Andy...

Here you are:

I agree!

Hi Ian I have new "short" front wheel brake cylinders for sale, if you are interested.

Check float needle valve height.

I have somewhere a Renault accessories catalog from the '70s that shows the dual pedal arrangement, to convert the R4 to a driving school car.

I make them out of polyurethane, in the lathe. Any good machine shop with experience in this material will be able to do it.

Nothing more is needed! You push the curved metal strip from its wide end to make it pass through the rectangular slot. Then you insert the bare cable end between this strip and the rectangular part. Now when you leave the strip free, it will catch the cable end because it's springy. Done!

Note that you can't measure CO value at full load on an MOT gas analyser, this one measures idle CO or low load CO value. Ideally, you need an AFR meter and check the reading on the highway. Malcolm, you couldn't be more right! Ethanol added to modern petrol makes the "known" stoichiometric...

The "classic French look" was yellow bulbs only. From a certain viewing angle, this makes the lens look yellow, but it was always clear.

It's 180g if you can find a practical way to measure it.

Out of curiosity, how did it break?
