View Full Version : bum wobble
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 ?? :nenau..... or anything else ?
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 ?
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.:lol:lol
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?

thanks rick , ive just had a look outside ( ok its dark ) but the front looks higher than the rear ..... any ideas rick ? .... ive done a press test on the shockers and they bounce once then settle

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

defo down on both sides equally
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 ? :nenau , cos the front end does seem light on steering , but then i suppose it will do if the rear is low
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

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:augie
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

pmsl @ sterling .....it does seem easier to get in and out of the drivers seat .. as for speed bumps , yes there are loads around here , but contrary to popular belief i always slow down over speed bumps

that would mean the front end is lower
could have been unlucky enough to have broke both springs
any knocks or bangs or odd noises when going over the speed humps

no karl , the front end is definately higher , i seem to sort of find it easier to get into the drivers seat , maybe its cos im used to it ? ... dunno ... but im almost certain its higher at the front because there seems to be more clearance from the tyre to the top of the wheel arch at the front as opposed to the back ..... hope this makes sense

Have you checked you haven't run over something at the front, :nenau
Maybe the Policeman who was sending you the prosecution.:doh
Could he now be a "Sleeping Policeman" ? :lol:lol
It does sound strange, the bottom hasn't fallen out of you bi-focals has it ? And it just looks sloping.
You haven't parked in someone elses drive have you?:doh

Pete, Have just had a look at your pics when you had your decals fitted and theres 1 of you standing/leaning on the side just before the the rear wheel, maybe if you had a look and tried and compared things in the pic to you ie where your waist belt is or knee height, shoulder height, anything really just pick a few and compare etc then this may help to see if its sagged at the rear, I must say that looking at the pics it dont seem that the arse is dragging at all in fact Id say theres very little in it from front to back,when you look at the pics.
Just a thought eh ?????
i agree, Pete, can you not go out over the road, and take a pic for us mate??
ok , ive been driving in it today , still a bit wobbly , my neighbour had a peek and said it looked a normal level height :nenau.... its like its softer at the rear if that makes sense ?
my brother phil has just taken it for a quick drive around brighouse ...... we will see wot he says when he gets back:rolleyes:
ok , phil just got back , he says its a pig to drive because " its a funny auto " :augie .... he also says it " twitches " when going around corners :eek: , he thinks it feels too soft at the rear too , but isnt sure exactly what it is :nenau

you got smiley's for wheels bloody hell where did you get them from as i want this one :eek: :thumbs
Hi Mr Brigg, the rear bump stops on the terrano are part of the suspension, as you load up the rear the large squashy figure of eight stops are soon reached and become part of the springs support. They do drop off, infact mine didn't have any when I bought it but I didn't know and had a couple of m o ts without them. When mine sagged at the back it was the spring holders which had rotted away. The bump stops are I believe £88 each from Nissan but I got a pair from ebay for £25.

Hope this isnt your problem. regards bri

Hi Briggie,
On my R3mR it always had a bit of rear end wobble that slowly got worse.
Two MoT's later and my local garage found the problem it was a bush on one of the two short rods on the upper part of the rear axle. To date only replaced one pair on the right side my mechanic did not do the other side as the bolts were solid.
Ought to have done both sides but decided to wait until they show signs of movement. Should have done both rods for balance but no feel of any problems now and bobble gone.
Milner Off Road supplied a set of Polybushes (Orange rated) and problem was sorted. On mine there are four such bushes on the upper short rods and four on the rear swing arms so there is plenty of areas where you can have some wear / movement.
The Polybushes are easier than the Nissan ones to fit and tighten up the suspension a bit.
