FAQs about rebuilding struts.

  • Is my strut rebuildable?

    Some struts are rebuildable and some are not. Many OE struts are rebuildable. Here are a few ways to determine if they are:

    • If the strut has a cutline groove stamped into the top of the strut body (painted area) and wording stamped that says “cut here.” Be sure not to cut any strut open unless it specifically has “cut here” stamped into the strut body.
    • Others may have a hex-shaped locking ring on the top of the strut body (painted area). Another way to tell if they are rebuildable is if there are threads visible on the outside top of the strut body (painted area).

  • What kind of oil should I use in the housing?

    We recommend using transmission fluid in the housing because the fluid’s color is red. This distinguishes it from the oil in the cartridge – which is not – and if there happens to be any fluid overflow, a determination can be easily made as to which fluid it is.

  • It says to fill the housing with 30 cc. How much fluid is this and how much should I put into the housing?

    30 cc is the equivalent of 1 fluid once. Start with this amount in the housing before you place the strut cartridge in. Use the cartridge as a dipstick. The body of it should have oil ¾ of the way up the sides when fully inserted. You may need to add more oil, in small amounts, until you reach this level.

    Gabriel cannot determine whether any particular customer is qualified to check or replace ride control, shocks or struts. Customers must make their own assessments of their experience, skills and knowledge and take responsibility for all results and if in doubt, seek the assistance of a qualified trained mechanic.

    Every vehicle is delivered with an OEM owner’s manual. If you cannot locate yours, several publications exist that will provide you with the specifications for the parts on the vehicle you are about to repair. Read the OEM manual specific to the make and model of your vehicle and the instructions that accompany your Gabriel product before undertaking any repair or replacement project. Always seek the advice or assistance of a qualified, trained professional when needed.

    Before starting and vehicle repair or replacement project, you must have the proper training, tools, equipment and experience necessary to safely and correctly complete the project. This is especially important for anyone attempting to replace a worn strut or shock absorber, because failure to remove the worn part or install the replacement parts correctly on your vehicle may result in personal injury or damage to property.
