Frequently Asked Questions: OE 14258401-00
Is this strut definitely the right side for my tailgate?
Right side is confirmed for this strut, which fits the rear of the tailgate. Left and right versions are not interchangeable, so fitting the wrong one will not hold the tailgate correctly. If you are unsure which side has failed on your car, or want it checked before you commit, use the quote route on this page and give your details there so the correct side is matched for you before you order.
What if the number on my old part is different?
A different OE number usually points to a different build or market version of the car. Check the model and the model year exactly as written on your registration document, since even a small change in build date can bring a different strut. Do not assume the numbers are close enough to work. If your document shows a different year to what you expected, matching the listing to that exact model and year is the safest way to order the correct strut.
What is the strut body made of and does that matter?
Check the side, the position and the fixings on your own car before fitting this strut, since its main body is metal and will not adjust itself if the mounting is slightly out. A rigid metal body needs the mounting points to line up exactly with the strut in your hand. Comparing it against the side, the position and the fixings on the tailgate itself, rather than against the listing alone, means the tailgate opens and closes as it should from the first fit.
Does this strut need painting to match my car?
No, this strut does not need to be painted or finished before fitting, and it is supplied in black. Have your old part in front of you before you order, and compare the finish and the fixings against this one, since that is the surest way to check it will match without extra work on your side. If the old strut looks different from what is described here, hold off ordering until you are sure it is the right one.
