Broken Shocker

[mudnut]

G'day, All.

Broke a rear shocker at the Grampians. I think it was caused on the way up the mountains. I had to dodge a DH racing down the twisting road. The Old Trol's body rolled a hell of a lot and we hit a pot hole as I steered back onto the road.

It seems a bit of a co-incidence that it has happened after fitting the coil tower brace which came with a 10mm urethane spacer.

I have a two inch lift fitted. Before I buy a replacement, do I have to take the spacer into account?

[mudnut]

This is the result.

Spoke to the local Pedders bloke, as the suspension is theirs and he reckons the shocker has "topped out". And a pair of replacements is $210 each for foam shocks.

Any input is welcome, cheers.

Yeah thats what it looks like to me as well,
get one slightly longer again to compensate for the DH's.
You'll need a pair as the other one will top out soon
Bummer and Koni's too GGRrrrrrr

I talked to Autopro, and explained about the spacer and was told I can get a pair of Munroe to match $200 in total. So that maybe the way to go.

The spring number is a Pedders number 7853 L. The "L" Denotes left hand side.

mudnut your shocks must have been on the limit if 10mm is all it took to render it U/S
Anyway $200 is not very painfull eh.

Do you need to measure full droop and full compression to pick the shock
or just full droop Doh yeah full droop I say that with a smile too lol

[mudnut]

I have no idea what or where to measure so hence the questions. The shocks and springs came from BA a while ago.

[threedogs]

I have 15mm spacers I want to put in [all around]
but will need to see first if shocks will suit it /

[mudnut]

I have placed a request for further information regarding the length at Autopro. I have fitted an old shocker for the moment.

Is there any markings on the outer housing from the coil sring?

[mudnut]

No, the only marks are from the broken pieces.

The spacer wouldn't make bugger all difference in the grand scheme of things..
Meassure the length you have from shock mount rod to rod, then meassure your bump stop to axle..
Subtract the bump gap from the shock length and that's the fully closed length.
Get a shock 10mm shorter for safety.

You have not allowed for the compression of the bump stop, a few tonnes compressing the suspension in a quick movement will compress a 120mm (rear on a leafy ute) bump stop to half that if not less, and that's only guessing.

Any suspension mod that allows the shock to fully close before the suspension does is going to fail, as is the other way if the shock is not long enough for reasonable travel and gets torn apart by over extending.

The Simpson Desert is notorious for destroying suspension because of the extremely rough terrain causing the suspension to travel its full range all the time.

Yea sorry I did mean the base..
But what bump do you guys run in the leaf utes.
Wagon fronts compress about 120mm. The coil rears compres about 30mm I think.m

[macca]

Its a rubber wedge 120mm from the tip to the chassis, fairly solid to take the hits I guess.

Being wedge shaped it would compress progressively, but I'll leave that to smarter minds to explain the science!
