bum wobble

briggie · 24-11-2010, 20:58

today while driving into halifax , i noticed that the rear of my car seemed " wobbly " .. so i stopped in a layby and checked the back of the car .... i pressed down on each corner and it bounced once then settled on both ..tyres have plenty of tread , ...... im a bit worried because it has to go for a mot shortly ( its first proper one since i bought it ) ..... any ideas ? ... ive had the front arb bushes done .... could it be the rear ones ??

..... or anything else ?

briggie · 24-11-2010, 21:00

oh , it seems to be sitting a bit lower than normal , ie the back is slightly lower than the front ..... or is it me worrying ?

Tyre pressure maybe

briggie · 24-11-2010, 21:02

last time i checked tyre pressures ( monday ) they were ...... 29 rear ..... 28 front

Could be your LSD Pete might pay to change the oil and make sure it is LSD oil, Rick

You don't have any half filled oil drums in the back do you.?
It would give the same symptons.

Wet salty roads are a bit lively, are both your rear tyres the same tread, pressure, type etc, as it could be the LSD working against you, and slipping on the wet road rather than slip the LSD, when was the last time you changed the oil in LSD?

Well, I counted any one of 16 places, bushes, links etc.
Well that's if it's the back of course.

Crow bar and an assistant springs to mind for this one.
I need to check my rear end, never replaced any bits there yet..
Mine is a bit lively when going down ridges in the centre of the road.

The problem is a bit of wear here that is acceptable and a bit more there ... all adds up, you may find it worse if you change speed quickly.

Yeh, but if it's suddenly noticably lower at the back, I'd be looking for some structural failure

Is it defo down both sides?
If not it could be spring mount plate at the top.

defo down on both sides equally

briggie · 24-11-2010, 21:54

ok , heres a thought .... what if it isnt the back end , and the problem is at the front ? , thereby making the front rise and making the rear seem low ?

, cos the front end does seem light on steering , but then i suppose it will do if the rear is low

kbekl · 24-11-2010, 21:57

take the spare engine out the boot lol

is the front sitting higher than normal ? is it that same amount of effort to get in and out of the drivers seat ??

the wobble could just be that you lost a weight off a wheel or some one has nicked them lol

take a pic of both sides if you have some street lamps out side

makeitfit · 24-11-2010, 21:58

The unusual thing is its the same both sides?
Have you been over any huge speed ramps Sterling?
The ht at the back has to be related to the springs and so poss you've lost the rubber spring seats

Broken both springs(unlikely), any bushes wouldnt fail all at the same time and even then could only account for a small difference

How much stuff you got in the boot Pete? I know you put your chair in there but I just remember when I picked your motor up from that un named scam firm that you had a load of paper stuff on board, Rick
