The flat rate for each side is about 1 1/4 hours, so two and a half for both. The upper mount is removed to do the shock, so there is no extra labour for that part to be replaced.
Monro-matics in Canada retail for about $210.00 the pair, so I do the job for about $350 without the mounts.
Air tools help a lot, especially with the spring compressor. But one slip with the compressor and you can ruin your whole day. Rent or buy a good one if you do the job.
Disconnect the brake line bracket, the tie rod end, the sway bar link, and mark the upper mount location on the inner fender. Remove the three nuts, and lower the strut down, and angle it out of the fenderwell. Install the compressor, and squeeze the spring down until it is loose. Remove the upper shock nut, the plate, and the shield, and the spring. Install the new shock in the strut, and reverse. With a good compressor it is not that bad of a job. Takes me about 30 -45 minutes a side when all goes well.
