Rear Arch Problem

[Karl 15 1 Cars]

Hi I have a recuring problem.that needs sorting sooner rather than later....

 

What it is, the passengers side rear wheel keeps scraping the inside of the arch near the sill and Ive recetly had it welded up to reapair the damage it isnt hitting the top of the inside of the arch just the front near the sill its only the passenger side. The car has been lowered by moving the torsion bar 1 spline itwas okay at first but is now becoming a expensive problem

 

Any ideas as to what it might be?

lowered by moving 1 spline?

 

oh dear... oh dear oh dear.

missing bump stops most likely.

either way we need a photo

 

could be many things, most likely however is the beam bearings are shagged, if so, the beam tube is likely to be shagged too as the trailing arm shaft wont be sat correctly in the tube

Are you missing the bump stop on the side in question and do the rear wheels sit centrally in the arch (and the same both sides)?

[Karl 15 1 Cars]

Ill take some photos now amf upload them

[Karl 15 1 Cars]

yes the bump stop is missing that side the wheel looks as tho its sitting centrally so is this just a small thing of a bump stop or something more serious as dan said

Also whatis 'oh dear' about the lowering method I thought that was the only wayto do it :/

Don't think those links are working... Unless you have to log in to see the pictures?

Needs the bump stop back first of all.

As for lowering, the "spline" method is a bit rough and only allows set amount of lowering. If you release the torsion bar at both ends, due to either end having a different spline count, it's possible to set the ride height to pretty much any variation you like. It's a bit of a shame some of the more experienced members above couldn't have taken 30 secs to explain that rather than posting stupid f***ing pictures.

I had this on my CTI. If you lower the beam it does tend to bring the wheel forward.

 

This kind of catching?

 

The wheel still looked central though

 

What might be the problem is that you are on 1.6 rear beam mounts and if you switchedto 1.9 mounts, then they are sided and will move the wheel back slightly.

 

1.9 mount on the left, 1.6 on the right

 

1.9 mounts have a D & G (not Dolce & Gabbana) but Droit & Gauche (Left & Right)

 

You can see how much they move the rear mount back as the sandwich rubber is still set for 1.6 ones here

Other way around, droite = right, gauche = left.

Thankyou For explaining that for me very much apreciated

 

Yes that is exactly what has happened so ill now replace the bump stop and switch too 1.9 mounts and hopefully lroblem.solved thanks again

how would you be avle to guage the drop though

[welshpug 1,646]

far far easier than the former method.

basically stock measurement between the damper bolts at rest is 322mm, move the trailing arm up with the bars removed fully till its at a desired point then insert the bard back in wherever they will go back in without force.

 

You will need to rotate the bars spline by spline till you find the right pair, one side will engage by 5mm before the other side, so with some gentle prodding of the torsion bar and pulling it out and rotating and pushing back in you'll soon find it, having everything clean of any corrosion and lightly greased will help massively

Excelent I will have to do this the correct way then thankyou very much for informing me of this

 

Also would these do the trick for the beam.mountshttp://www.bakerbm.com/205.php?data=suskit205a I cant seem to find 1.9 specific ones

those mounts aren't what henry/tom have highlighted - they're for the rear of the beam where there would normally be a rubber sandwich bush. the teflon bushes are what go under the beam specific mounts and require pressing in iirc!

 

to be honest if this has all started from just lowering your beam, and no other alterations done to the beam, you're likely to have the standard beam mounts there so not to worry with them.
