Bilstein shock bushing order

I am in the middle of installing Bilstein shocks and want to make sure I get the top/bottom mount bushing and washer orientation correct. The instructions are very unclear. This seems to make the most sense to me.

It seems to go
  • Thick smaller heavy washer lip pointed down
  • Bushing wider side down
  • Thinner larger diameter washer lip pointed up
  • TURRET / Plastic center tube in between bushings
  • Thinner larger diameter washer lip pointed down
  • Bushing wider end up
  • Thick smaller heavy washer lip pointed up

Same for bottom less plastic center tube

Upper


Lower

That's it. You are sandwiching the bushings to hold them in place.

No the dished washers are upside down in your picture. Flanged washers correct.
If you think about it, the way you have them in the pic does not allow room for the rubber to squeeze out.

I'm not sure which you are saying is upside down? Outer or inner?

If the outer washers were flipped, the lower one on the upper would crush the mud guard. Also there would be no point to having that lip. Also the factory top washer faces down like that. (My top hats are seized)

If the center ones were flipped, they would face each other and crush when tightened. Also wouldn't allow room for the turret or lower mount to be in place.

The middle washers are oriented correctly(the ones that go against the shock mount). The outer(top/bottom) washers need to be flipped. Look here about 1/3 way down the page. Discovery I Rear Axle Suspension - Rovers North - Classic Land Rover Parts


Also, those bushings do not look correct. I've never seen tapered bushings that go on the pin mount. You sure those aren't for the rear upper eyelet/loop mount???

The tapered ones go in the upper rear, and the flat/cylindrical ones go on the lower/pin side.

That page is for a Discovery. Looking on this page it seems the top and bottom washers are orientated correctly. What is the point of that cup shape on the washer it if it was facing away from the bushing ya know?

Front Axle Shocks & Springs, Suspension for Defender - Rovers North - Classic Land Rover Parts

Also I never removed my shock top from the turret, my suspension looks original, and it appears that the washer is oriented the same direction as I have mine. I can't get eyes on the bottom washer without cutting the shock shaft, the nut is too seized. Also if I was to flip the bottom one, wouldn't it not crush the metal shaft guard?

These are def the correct package of parts for the front, I have the rears already laid out with their proper tapered upper bushings in place. These ones are too small. Whether or not they are supposed to be tapered is another question but all my packages came with tapered bushings.

Both packages of fronts had the same parts contents. Same for the rear lowers.

EDIT - This shows the hardware contents, shows tapered bushings

Maybe I am wrong.. I am going to call Bilstein in a few minutes, they were closed when I was working on it last night.

Bilstein's instructions look clear (pages 5 - 8). What is the type # stamped on the side of the shock?

That's the thing. Neither my fronts nor rears have a type # on them. Part number, which doesn't match up with install at all.

My buddy and I looked everywhere for a good while for a type number. Not on the shocks or packaging. My shocks have made in USA on them, I wonder if the German made have a type number.

Fronts are 24-188296
Rear are 24-188302

You do know that Discovery, RRC, and D90 all share the same shock mounts, right? Your link even confirms that. So even though that install pic I. Linked to says D1 its the same for D90. As far as those tapered bushings I've never seen that. Maybe that allows the washers to be installed like this ( ). IDK.

I just spoke with Mike at Bilstein USA. Apparently they don't put the type number on the shocks anymore (WTF!?!). Anyway our trucks are most similar to Type 8 on instructions for future installers, with the exception of the tapered bushings and center rod on the top.

The way I have everything oriented is correct EXCEPT I have my bushings upside down. They are supposed to create an hour glass shape. Counter intuitive IMO as you would think large diameter bush side matches larger diameter washer, but I will trust Bilstein on their own designs.

They also stated they used a tapered bush (vs standard straight) on this model because of the increase shock rate to help soften the ride a bit.

You know what I meant. Don't you have a photo contest to judge....poorly?

Did they meantion how the washers in the rear lower get installed? I would think installing the curve towards the bushing the washer would contact the cup..
