Replacing rear lower spring mount (trailing arm)

Was replacing the springs on Myrtle and when removing the rear spring on the near side the "spigot" (round tube) that the bump stop hits against on full travel dropped off.

What was left looked like this,

Brickwerks do a replacement http://www.brickwerks.co.uk/shop?page=s ... ory_id=140 which is £20 odd but by the time you add shipping and the wait I reckoned its easier to make my own :D

So, using the original as a template I cut a disc out of 3mm plate and then relieved in the rebate for the pigtail with a hammer and bolster (the BW one doesn't have this - its just flat plate.

Image

Then cut a length of appropriate size tube and welded this to that plate before topping off with some 1mm which I then dished to replicate the original.

Image

I had rubber spring mounts on mine which locate with a small hole so needed to drill this into the new plate as well.

Cleaned up the trailing arm and the drilled some 8mm holes in the new spring mount before puddle welding to trailing arm.

Image

Wizz over with the grinder to tidy up then ready to fit new springs.

Image

And this is what the original looks like on the other side (which will need doing soon as well :( )

Image

Yummy, these are the new Eibach -40's that Baxter has had specially made for BW, couple of pics for comparison to JK -60's.

And fitted

Also trimmed a couple of rings off the front bump stops and the ride is much better, not a big fan of slamming on these so -40 is ideal for me :ok

Job done.

Anyone want to buy a set of -60's? :D

And that, in my view is the RIGHT way to do that job, not weld on something that isn't a close copy. Great job. The hammered recess was a nice touch. You do wonder though, why VW didn't make a kind of rubber or nylon skirt for the spring locator. Expense I suppose.

Air suspension (as used on trucks) would be a nice alternative on the back :D

Cheers CovKid :) I like to get stuff as original as possible.

Mine did have a rubber pad (about 3 mm) on the bottom which I think was OE as the plate mount's were drilled for the rubber pimple to fit in that keeps the pad in place.

Now, I don't like slamming, but if I was to slam then air would be the way i did it - I do have a passing glimpse everytime I go to a VDub show and see the Golf's and Jetta's bouncing up 'n down :D

Say no to low. Good work on the trailing arm, thats the sort of job that can really eat into your holidays. The 'man round the corner ' is looking after my trailing arm - will keep you posted, should be done tomorrow. :D
