2005 XT Suspension Questions


Recommended Posts

Apologies if these have been answered before but I seem to be getting conflicting answers during my searches!

I have a 2005 XT, I want to use it for towing a single axle trailer with a Cooper S/Punto race car, however when I hooked the trailer up to the car, it was far too low, the lowest point of the trailer was about cm off the road (the jockey wheel), when we tried to tow it began hitting the road! I looked under the car and the SLS has been replaced with Monroes suspension

The rear suspension is lower than the front, from reading on here, the rear should be level if not higher than the front. However when I went to Peddlers website to look a their options, it says it will restore the factory ride height of 665mm (link: https://pedders.co.uk/pedders-subaru-forester-sg-ezifit-rear-suspension-conversion-kit-standard-height-803040), however when I measured the rear ride height of my car it was 680 mm from the ground to the top of the wheel arch, the front measured 750mm from ground to top of the wheel arch.

Is peddlers correct? Is my rear ride correct? Surely it cannot be right if the jockey wheel is hitting the ground?

I'd also like to go for the KYB, as it seems to be the better option from reading on here. But given I would need to order everything individually, would anyone be able to tell me what parts/part numbers I need? I want to put all new parts in so won't be reusing anything if possible. So with that I mind I think I need (for the rear at first anyway!):

A. Strut B. Coil Springs C. Top Hat D. Dust cap (?) Is there anything else I might be missing? Given we're all locked down, I'd like to give this a go myself having never worked on suspension like this before!!

I would suspect you have wrong springs on the monroe shock, the spring is specific to SLS or non SLS and is a chance SLS spring been used and that result in low height and sagging quickly with trailer tongue weight .

Do your measuring again as service data diagram below as measuring from ground no good as different tyre/wheel combo's give different heights and pedders stupid for using measures like that .

For guidance look at this thread >

 

You will need buy a spring compressor tool and may also need buy new rear drop links as if rusted they easier cut off and new fitted  (If both sides of rear off ground when doing the job then don't really need disconnect drop link but lifting 1 side at a time drop link does need be detached at one point)

Thank you very much for the detailed replies!

I mainly want to replace the top mounts due to piece of mind/ I want to learn / slightly terrified of trying to take them off the old springs! I do need to measure again when I get a chance. I've begun spraying WD40 on the bolts that I'll be taking off, trying to make sure nothing snaps or really resists me. I plan on jacking the car up from the rear diff so both side should be off the ground. As I understand it that should mean all I have to remove are the two strut bolts into the hub carrier and the 3 in the cabin, am I missing anything else?

Generally rear top mounts in great order as they do very little, if heavy corrosion or rubber dry rotting then wise replace .
Save yourself good £80 using current top mounts if good and they easy remove, spring compressor no real drama if done with some thought such as oil threads on spring clamp tools and seat them properly and evenly  .
I done some work in japan many years ago and salvage guys use to strip struts with impact gun with strut lying cardboard and feet resting on top hat while zip nut off, strut doesn't shoot across the floor like a torpedo but needs be done with some basic diligence .
If you got an air impact or Battery impact you undo strut to top mount nut easily, without that you have improvise such as using grips on strut rod (do not damage chrome surface and only do on new ones as last resort) or by making/buying a pass through tool (old socket with flats cut/ground for wrench and access through drive square can work)
Like you say very little disconnect and should be easy as been done fairly recently although by looks of vehicle rear height with wrong new springs (probably sls spec springs) or old sls springs reused .
An extendable 1/2" ratchet such as this can be very useful for strut bolts if your tool kit bit minimal, they quite decent heavy duty ratchets if lightly grease ratchet mechanism and pinch the clevis torx screw good and tight .

I have a similar problem with rear suspension on my 2006 2.5XT.
After MOT fail last year I got original rear SLS replaced with cheap aftermarket parts (I did not know about SLS then).
Now I have the low rear ride height problem.
Looking at resolving this with parts from either subaru4you or pedders.
Is there anything to choose between the two?
Pedders are quite a bit more expensive but I might not mind paying extra if they are better quality/more reliable.

Many thanks in advance for your advice

Get the Japan made kyb excel G shocks and the matching non sls RA6028 springs and you done proper for under £200 .
https://www.ebay.co.uk/itm/323874493110?epid=248894226&hash=item4b686c92b6:g:XXsAAOSw0eNdQ~n5
If you used original springs that why it still sags and if replacement springs sls spec then it still sags.
Hard beat KYB and the shocks and springs as listed in this thread are proper non SLS spec that give ride height in service spec range .
What shocks did you use ? is likely just the RA6028 springs on shocks you got will give correct height .
Pedders are decent enough but they overpriced and companies are milking fact most people clueless and assume it hard get other normal options which isn't the case .

Embarrassed to say I have lost all records of the shocks I used!

I suppose it would be worth trying the RA6028 springs with the shocks I have and if not satisfactory then order the kyb parts.

Sounds like a plan

I have seen some of the cheap off brand eBay struts turn out short as the spring perch sits lower than should .
most of the time it down to people using the wrong springs (new SLS springs as if part match via vehicle reg/vin that what computer show correct part) or reusing the old SLS springs .

If you like saving money do not buy any cheap brand suspension parts because they are all garbage either in fitment/spec or durability .

Thanks for getting back to me.
I retraced my steps online and found the parts I used!!!
They are these Ridex shocks;
https://www.buycarparts.co.uk/ridex/8002080
https://www.buycarparts.co.uk/ridex/8002079

Any idea if they will work with RA6028 springs?
 

Thanks again for your patience in answering all things shock related 🙂

Not a shock I recall dealing with, looks about right length in images .
Do you know the springs you got .
SLS springs have roughly 12.5mm thick coils , light duty springs 13.5mm and the RA6028 are 14.5mm
rust and coatings differ measures fractionally but if you measure under 13mm you can be pretty sure it sls springs and if under 14mm light duty springs and benefit from RA6028 .
Lot of the cheap and even known brand springs are not great spec and can be slightly short or lose height in couple weeks of use .
Only ones we genererally use are KYB springcoil custom springs or oem and perhaps kilen suplex when needs must .

I must still have the original sls springs in there as I didn't buy any others. I went for a quick fix at the time as I had a lot on. The garage who did the work just swapped the shocks but kept the old springs in. This would explain the sag of course. Unfortunately I disposed of the old sls shocks as I didn’t realise they have recondition value. So I will try the RA6028 springs with Ridex shocks and see how I get on. Will post some before and after pics for future ref.

Thanks again for your advice 👍

should be an easy low cost fix then.
Use the image in post above which subaru service manual data to measure your before and after heights .
Drive a few days before do final height measures .
