Vibration.rumbling

[muddymart]

I picked the car up today from the garage , its had new gas suspension and heavy duty springs all round, and polybush kit fitted,

I'm getting a strange vibration/rumbling that was not there before it went in,

could the prop uj's have worn out/dried up if the car has had poor suspension for a couple of years? I'm only saying this as its quite high compared to when it went in , the drive , cornering and stability is unbelievable,

Thanks in advance

Martin  :D :D

sound like the prop uj put new one on should be fine. mate of mine had a rumble and this week chewed front prop up
naste mess underneath and lots of smoke from tyres lucky he was only going slow

Yes if it's run for ages on tired spring then the UJs will have run in in this condition, now you've lifted it (even if backto standard) then the UJs will be out of their "comfort zone" and it's very common for them to expire.

Is it lifted above standard, if so by how much?

standard should be 790 mm from floor to eyebrow with 235.70s on.

HI RRB again !! ;)

I just went for standard height gas shocks and hd springs all round, but just looking at the car now, the springs and shocks must have been well tired, and they were on the car when i bought it, so your guess is as good as mine, no receipts in the folder for replacements over the last couple of years.

You'll find that it settles a bit over the year as your new spring settle in then.  Don't worry, they should do that.  You'll find it rolls lees at the moment too ;)

When it's warmer, try measuring the eybrow height, another indication is the front panhard rod, it should be roughly level across the axle on a standard car.

well what a difference new shocks,springs and  a polybush kit makes, should be nice to tow the caravan now ! , I'll just keep an eye on things see if it does stop, I'll re grease them tomorrow and have a good nosey round,

thanks  :D

YEs it will be nicer to tow with for sure, the gas shocks really help.

Here's onw for you though, when youl drop the 'van on yo'' find the front end goes lighter, if you get any vibration (or it gets worse) then it's the front end, usually the gearbox UJ on the front prop.  Though if course the extra weight behind the car does mean it's working harder.

worth going round and checking al nuts have been nipped up right. sometimes nuts slacken after a bit of work has been put on them (i.e. you "testing" the handling :twisted:)

but the favourite is the front prop UJ, mine seems to eat one every 6mths!
