Seat Runners - Refurb or Replace?

[L66TEY]

The seat runners on my 2010 R300 are looking worse for wear and were not moving until I unbolted them and gave them some WD40 to assist them. 

Whilst they are now functional, the paint has come off them, hence was looking to refurb them. 

But to do that I need to figure out how to separate the top and bottom. 

Hence, does anyone know the method/ technique to "split" them open?

With thanks

Definitely a refurb on those. I would wire brush, Kurust (or whatever is your preference) and finish with Simoniz tough satin black. I also wiped mine over with Lanoguard.

I wouldn't take them apart as I can imagine they will be a challenge to get them back together!

If you're that bothered I'd rub them down and spray paint the outside. They'll need a good de-grease if they've had WD on them.

Thank you Gents. 

I've subsequently decided to go for the refurb approach. 

Although whilst looking for replacement ones on CC Parts website I located this "support". 

As I have lowered floors and don't have these "support" plates Im now convinced the reason for the runners being so stiff and difficult to adjust, is not due to the runners themselves - but instead down to the fact they appear to be touching the angled wall of the lowered floor hence it's the metal to metal friction that is causing the runners to appear jammed. 

Having test fitted the runners back in with some washers to space the runners off the floor by circa 2mm they are no longer stiff to operate. 

Hopefully this info will help others to resolve the ever jamming seat runners
