Rear Jacking point
Rear Jacking point.

The jacking point of a heavy vehicle is very important. It is so easy to bend the chassis if this is not correct.
In the photo above the jacking point is the support bracket, retaining the wheel spring, placed to the front of the rear wheel. At the base of the jacking point can be seen a hole, which will fit the jack supplied by Peugeot for this vehicle.
The front of the vehicle is jacked up in a similar manner, to the rear part of the spring bracket. This also has a similar hole to contain the jack.

While jacking a wooden spacer should be considered, as when jacking ,the rust sealing insulation can be ripped off with it's inherent problems.

Hi All, 

        When looking for roadsprings, check your yellow pages or phone book for a Serck Radiator depot, some years ago they took over the Woodhead spring business.  I did considerable business with them obtaining new and exchange springs for vehicles ranging from light vans to 40tonners.  Taper leaf springs are new only, usually no exchange, things might have changed, but certainly worth a try.  By the way, if you have a friend in the trade, see if he will write you a "cash only" order, you will probably get some discount.
