    Default Feeling rather bouncy

    Lately my 1.9 120 Veccy feels rather bouncy and a bit light on the front end. The steering feels a little lighter too.

    I had all 4 springs replaced in May after I found a broken front spring and then a broken rear spring was identified during the MOT. The replacements are Lesjofors. I'm told that the springs that were taken off the rear (old ones) were actually the wrong springs and the car now sits around 20mm lower at the rear on the new springs. This does make sense, because it was noticeably higher at the rear than the front before but I thought nothing of it.

    A few weeks ago (after the springs were changed) I noticed pretty bad understeer on high speed corners and the car seemed to be tramlining a little. As I'd had the new springs fitted I took the car to get the tracking checked (only a two wheel check). Tracking was only slightly out, but when up on the ramp they found both front tyres were near enough bald on the inner edge. This surprised me because this wasn't picked up on the MOT in May and I can't imagine the tyres have worn from passable to bald in that time. They were replaced and a slight adjustment was made to the tracking.

    The understeer has now gone, but the front end feels just as light. The tramlining hasn't completely gone either, but it's a lot better than it was. I'd say the steering is less responsive than on the old springs. There's no play in the steering wheel, but I definitely have to turn it further. I recently did a 90 mile motorway trip and it felt like I had to constantly make small re-adjustments to the steering wheel because it felt that light. It wasn't windy, but it almost felt like when a crosswind blows you offline.

    I don't know whether the problem is suspension related (I suppose the Lesjofors springs could just be a little less stiff than the Vaux springs), or a combination of suspension and steering. It's a nightmare driving down B roads because I'm just bouncing up and down.

    I've checked the power steering fluid level and that seems ok. I've also checked the shocks and there's no apparent damage - no air noises and the car settles ok if you press down on either side and then release. No clunks or other noises either.

    I'm stumped as to what else I can try. Would a 4-wheel laser alignment help my woes at all? Or am I looking at putting it into somewhere to get a complete steering check?

    Is your car an SRi? its also possible the springs they have fitted are for the wrong front axle weight.

    Does it look lower at the front now since the springs were added? Im surprised they said it was the wrong springs on the rear as there are only 2 kinds of standard springs, Sports and Non Sports. The Sports springs option are 15mm lower than Non Sports and yours being a non sports model should have the non sports springs, for a comfort ride. Mine has non sports springs and it does sit ever so slightly higher at the rear. Its also possible that they have fitted springs with the wrong front axle weight too, this could account for the bouncy front end.

    Front still sits the same. The distance between the tyre and the top of the arch is about the width of my palm which seems right. The springs were supplied by a local motor factors and I checked the Lesjofors part numbers were the right ones for my Veccy before they went on.

    I'm going to get hold of the part numbers again and double check everything.

    Thought I'd bump my old thread instead of starting a new one. The problem hasn't gone away - the steering still doesn't feel right. I had it checked out by a local mechanic a few weeks back, he checked things like springs, shocks and track rods but he couldn't find anything noticeable wrong.

    However, I've recently noticed that I'm getting a creaking/squelching noise when driving along now. This leads me to believe possible front ARBs on their way out.

    Would worn ARBs cause the handling problems I've been experiencing?

    the arb itself wont be worn, maybe the arb bushes or droplinks, droplinks usually knock when the rubber seal is gone

    id be looking at the spring weights and front shocks tbh
