Read before following any guides
Obviously safety is paramount. These guides are all written by members who have done the jobs themselves, none of whom are professional technical authors. Therefore, they are to be read on the merit of items that will assist you rather than a precise 'follow this to the letter' type guide.
Whilst every care is taken to ensure the accuracy of these guides, you should satisfy yourself that they are applicable to your vehicle, you have the necessary skills to carry out the task and that you follow the usual safety procedures associated with working on any car. That is, you secure the vehicle using brakes, chocks and wedges where necessary and that you NEVER work on an car supported only by jacks. Always use axle stands positioned appropriately.
If you have any doubts regarding safety, ask BEFORE you attempt any job on your vehicle.
None of these guides are endorsed by the owners or administrators of this forum. You follow any of these guides at your own risk.
