Lotus Esprit S3

Front Suspension Dismantling


Picture shows nearside suspension prior to dismantling. The car is resting on axle stands positioned under the crossmember. A wooden packing piece is used to protect the chassis – just visible to the right of the steering rack boot.

The anti-roll bar has already been detached from the chassis and opposite suspension link.

With the split pin removed, the hub nut can be undone. ingress…

It should not be tight.


On this car, the braking system had already been drained and new

flexible hoses were to be fitted. Here, the rigid line coupling is undone

with a 13mm spanner to allow…


… the flexible line to be detached from the chassis bracket.

A 15mm and a 17mm spanner will be required.


The flexible line can be detached from the brake caliper in the same

manner. Use a 19mm spanner or socket to loosen and remove the

two bolts securing the caliper to its mounting, and remove the caliper.


With the caliper removed, the the same

hub nut can be removed to

allow the hub and brake disc to

be lifted off.

The inner grease seal has been

prised from its recess…


… and here the bolts that the same

secure the brake backplate

are being removed with a

13mm spanner.


Removal of the two lower the same

bolts (14mm) allows the brake

backplate and the steering arm

to be removed.

The front bolt has a nut on the

back…



With the backplate and steering arm removed, the brake caliper

mounting plate can be lifted off. This method saves having to disturb

the track rod end if it does not need replacing.



…and the two bolts that clamp caliper

the top wishbone to the top

balljoint (not shown but

should be obvious).

Then the upright can be lifted

away from the lower link.

The trolley jack is easing the

load off the trunnion and top

balljoint mounts to make

extracting the bolts easier.


With the trunnion out of the way, it is now possible to gain access to

the anti-roll bar end nut (a Nyloc) with a 19mm spanner.

It may well be fairly seized.


On this ARB the rubber bushes are completely wrecked. Note the

two washers (one with a tapered side to the centre hole) and the

distance piece (tube) through the centre of the bushes. It is also

possible to make out a crack in the Nyloc nut…!


Loosen the upper and lower the

damper mountings, then install

a pair of spring compressors

(not visible here).

The spring can then be

compressed…


Once the spring is under a the

degree of compression,

remove the damper top

mounting nuts and bushes,

prise the damper out of its

upper mounting and compress

it down into the spring.

Picture shows a large spanner

being used as a lever to push

the damper down.


With the spring and damper the

disengaged from their top

mountings, the spring can

be simply lifted off the

lower link.

Removal of the damper lower

mounting nut and bolt will

allow the damper to be

extracted from the link.

Note that although there is a

rubber spring seat in the top

mounting, the lower end of

the spring sits directly on

the lower link platform.


Removal of the pivot bolt the

and nut will allow the lower

link to be removed

from its mounting.

Similarly, the two halves of

the top wishbone can be

removed once their pivot

stud is extracted. The bodyshell

has holes in the foot-

wells to allow access for

sockets, drifts etc.

Note that the pivots may well

be rusted into the bushes

and/or the chassis.
