Front Shock Fitment: Alfa Romeo

Step by step replacement guide for 01.11 Mito Model

With nearly 18,000 of these models on the road in the UK, the chances that your workshop will be faced
with a shock absorber replacement are fairly high. This job should take roughly one hour per side and should be undertaken following our expert instructions.

Getting started

Remove the tyre. Now release the ABS sensor cable from it’s clip, then the brake hose (see Fig 1).

Undo the clip on the left and keep it safely stored (see Fig 2).


Then undo the brake hose clip (see Fig 3).


Raise the height of the vehicle then remove the bottom two bolts from the strut (see Fig 4).

Strut assembly

Under the bonnet, remove both windscreen wipers and the scuttle panel (see Fig 5).


Loosen the top nut and, whilst supporting the strut below, remove the nut and lift out the strut assembly (see Fig 6).


Use a good quality coil spring compressor to safely disassemble the unit.When assembling the new KYB shock absorber, coil spring, protection kit and top mount, check the end of the coil spring is aligned at the correct point on the spring seat (see Fig 7).


Gripping stuff

Ensure you tighten the top mount to the correct torque. It’s essential that you never use mole grips to steady the piston rod whilst assembling the unit – the grip can damage the smooth chrome coating on
the piston rod which will result in it not having perfect contact with the oil seal, causing premature leaking (see Fig 8).

The assembled suspension unit can now be offered up under the wheel arch and fixed in position from the top first, tightened to the correct torque. Use a small jack to support the wheel hub weight (see Fig 9).

Lower the vehicle and finish tightening the top nut to the correct torque. Then you can replace the bulk head, windscreen wipers and scuttle panel, not forgetting the small clip to the side of the bottom bracket see Fig 10).


Always fit in pairs!

KYB advises that you check the wheel alignment after the shock absorber is fitted to the vehicle and that shock absorbers and coil springs are always fitted in pairs.

Can one engine oil be used for all makes of vehicle?

Comma explains why you should beware the ‘one-product-fits-all’ trap.

Comma periodically issues ‘Tech Talk’ training and information bulletins to help workshop technicians stay abreast of the latest developments and applications in lubricants, coolants, brake fluids and maintenance chemicals.

A recent bulletin reflects on how the once common practice of relying on a single barrel of 10W-40 for use on virtually every vehicle service has had to yield to strict ‘selection by application’ disciplines dictated by modern exhaust after-treatment systems based around three-way catalytic converters (CATs) and diesel particulate filters (DPFs). Such systems are highly sensitive to unwanted sulphated ash, phosphorous and sulphur – so called SAPS – in exhaust gases. It’s a problem that was addressed by ACEA when it introduced the ‘C’ category of reduced or low SAPS oils.

A suitable fit?

Headlined ‘There’s more to oil than “C3”, the bulletin cautions against stocking a single product – in this case ACEA C3 low SAPS engine oil – for use on all vehicles. It says that even though an oil is legitimately coded C3, it is a mistake to assume that it will be a suitable fit for every vehicle requiring an ACEA C3 oil.

As Comma points out, VMs now demand something very much more ‘bespoke’, and have their own distinct formulations for the ACEA C3 oils they specify for their engines. It is also the case that ACEA C3 isn’t only used with 5W-30 grades – certain Alfa Romeo and Fiat engines require ACEA C3 as a 5W-40 grade.

To illustrate the point, the bulletin uses spider charts below to show how certain oil specifications of VW, GM and Mercedes Benz differ greatly, one from another, while still conforming to – and in some areas exceeding – the ACEA C3 performance levels. The bulletin draws the conclusion that, by itself “ACEA C3 doesn’t always match VM specification.”

Trustworthy application data

With VMs’ lubricant recommendations now widely written-in as warranty critical requirements, the safest way to ensure correct selection is to use an up-to-date and trustworthy application tool, such as Here, technicians will find complete ranges of Comma engine oils, antifreeze and coolants in which they can have total confidence, covered as they are by the brand’s unique 100% ‘Compatibility Guarantee’ and embracing all European vehicles dating back over 30 years.
