Land Rover Defender 90 renovation – front door check strap slider


Due to ongoing water ingress issues, which I will detail when I have defeated them (!), I had occasion to remove the cover of the right hand front door check strap slider. For information, the cover is the plastic triangle in the last image, the check strap is the bronze coloured piece of metal in the lower right, which stops the door swinging too far outwards. Underneath was not a pretty sight (see the first image) – probably year’s worth of rust! Well, I decided to renew the whole of this assembly. It was easy enough to do this (see the parts list below).

But, first I thought I would experiment with some minor paint repair. So, after scrubbing away any rust debris I applied Kurust to the rust in this particular part of the bulkhead. Then, I sprayed successively Hycote “High Build Grey Primer”,  Land Rover “Epsom Green” spray paint and Land Rover “Clear Lacquer”, leaving each one 24 hours to dry. Not much I could do about the surface damage to the metal due to the rusting but at least it had a better paint finish afterwards. Ironically, installing the entire check strap slider and cover masked all of this work.

  • WA106042 – washer M6 x 2
  • MWC5759 – check strap buffer x 1

  2. What was the bigger bolt that holds the plate onto the bulkhead?

    I have a TD5 and it appears to go straight through with a nut inside the engine bay covered in sealant.

  3. Yes, there is a bolt which goes through the check strap slider (part MWC5018) to the bulkhead – it goes through the angled “tab” part at the bottom of the slider. The relevant page of the “Land Rover Defender 90 110 130 Parts Catalogue 1987-2006 MY” book (page N158) does not specify it. I did use a new stainless steel bolt, washer and nut (not Land Rover parts) but I can’t be sure what diameter it is. Looking at it today I think it is M6 (but can’t exclude an M8), probably of length 2-3 cm. Good luck!

    • Hi, im new to getting ‘hands on’ with fixing/replacing parts on my defender and I came across your postI’m trying to remove the rh front door check strap slider on my 2004 defender but can’t seem to be able to get access to the bolt which goes through the check strap slider (part MWC5018) to the bulkhead (through the angled “tab” part at the bottom of the slider) I’ve tried to access everywhere I can think of without taking anything also apart.

      Is this accessed from the wheel arch, or from the engine bay itself
      Any pointers would be greatly appreciated 👍

  4. I’ve had a look in mine (1999), and the bolt holding that slider goes through to the engine bay, at the top right side (on a right hand side vehicle). I have uploaded a picture of this above. The stainless steel nut and washer in the centre of the image (seen just below the mass of wires) is what is securing it. Good luck!
