volvo estate / general question - standard Suspension springs vs progressive springs - Paul G1pdc

good afternoon.

I am in the market for a pair of rear suspension springs (one of mines broken)

spending a good hour last night playing on the net shows a huge market in lowered springs and various other types.

I'm not after a lowered set of springs, but theres 2 other types that spring!!! to mind. either stay with the standard ones fitted or try a set of "progressive springs" they seem popular if you do a lot of load lugging (mine lugging is limited to family holidays loaded to the roof and even a roof box.+diy making the rear of the car a little saggy...

just asking really if anyones tried these progressive springs (made by MAD and others) or if its only really worth sticking standard ltems back on the car.

thanks for any advice/pointers.

Paul.

What sort of model Volvo are we talking about, been into this on the 7/9 series, but not later stuff.

Progressive springs? I'm surprised Volvo estates haven't always been fitted with them - mainstream manufacturers like Ford and Vauxhall have used rising rate springs for a couple of decades, not exclusively on estates either.

The OP mentioned MAD - they also make auxilliary springs which can be added to the existing springs - they're particularly useful in towing when the boot is already full - I've had them fitted in a couple of Vauxhalls and they certainly do the job - the ride isn't any harsher but they did make the rear ride higher than standard when unladen which makes the steering heavier as the castor angle is reduced.

I've also had air-adjustable dampers on a Vauxhall and a number of Volvos have used the same system with either manual adjustment from an air line or fully automatic with onboard compressor to give self-levelling rear suspension.

Haven't seen air on a Volvo, newer ones out of my budget, i had older RWD 7 & 9 with self levelling rears, self contained (Boge iirc) dampers, simple as can be, the car would squat as you loaded it, by the time you'd driven it a few hundred yardsor even bounced it by hand the dampers had pumped themselves up to normal ride height, the damper effectively a second spring ....interestingly the non self levelling estate's rear springs were stronger rate than the those self levelling damper assisted models.

As an aside i wonder then if the self levellers had better ride quality when unladen as a result, i don't know cos the estates i had were SL's.

A sight simpler system than all the pipe work and plumbing some use, new self levelling damper units seemed expensive when they wore, but compared to the 4 figure sums involved in overhauling air/hydraulic pumped self levellers they were cheap as chips.

Example...MB's with air suspension new dampers alone are around a grand a corner, luckily the do last a long time and recently overhauled units have finally become available, not from your MB palace mind, enough potential expense and worry to put me off considering one anyway.

My current Hyundai and previous Subaru have/had self-energising self-levellers which work well - on the Subaru the spring rate was softer than non-levellers but on the Hyundai they're stiffer - go figure.

IMO, manually adjust air dampers are the cheapest to buy, maintain and replace - sadly £800-1000 is a "normal" figure to replace each side for self-energising self-levellers regardless of the brand.

HI...

in the end went for the easy option (well easy-ish...read on), standard volvo replacements and in most cases they are actually cheaper than the aftermarket items...and as the originals lasted 100k hope these ones will as well....

problem was......I rang the main dealer and gave reg. number and chassis number model, year etc etc,....that wasn't enough......they still had a choice of four springs.....so I had to get the colour markers from the springs themselves....ie remove the wheel clean the mud off and hunt for the painted markers......job done.....turns out my end of line Phase1. model uses Phase2 springs....

looked at the MAD web site, and there products get some good reviews with the caravaning and towing sectors.

Paul.

Think you've done the right thing Paul, can't beat the correct part, and you keep the ride quality.

From the MB forums, those who try to go aftermarket usually end up faffing about buying levelling pads and all sorts to sort ride height issues, often ending up back at MB for springs that were cheaper than aftermarket anyway.

Give 'em and surrounding area a good slosh of waxoyl by brush whilst you're there maybe.

hi Gordon.

good idea, didn't think of the oil thing...all the old cars I buy ways get a quick spray of gloop underneath, guess when you own a metro the mk2 escort at first cars you Hate RUST. thus we had a rust free puma and mk3 fiesta....how rare where those...haha....rear arches on both of those used to rust like 1970s fiats/lancias......

the puma used to have wheel arch liners a little like the 99p plastic car mats you used to be able to buy plastic and with nobles,,,i.e. the mud used to stick to it and sit there....... When looking at dealer cars for sale, they often say all the cars have been valleted hmmm you then run a couple of fingers under the rear wheel arches and loads of mud falls out.....always good to embarrass the sales man...

and a thin smear of copper grease over the back of the ally stops them corroding to the main hub...

once bought a copy headlight for a pug 205 it was a slightly grey in colour..and stood out a mile once on the car,,,,,so took it back and bought the proper part....
