Bump!!

Hello?

[Xulfiqar]

the springs are not bent, they are made this way. many cars have such springs, wider in the middle and thinner at the ends. and if you cut your springs you have to be very very careful as to not overheat the spring wire, it will lose the elasticity - if you cut correctly your wprins will end up harder than original.

But why cut them? - new springs will settle down in a month or so by themselves.

Thanks for the reply guru!
So what do you propose?
Should I wait for a month and then report back?
Its been 2 weeks since I got them changed.
The thing bothering me is the abnormal gap between the front tyre and the fender.
Even if there is one person sitting at the back seat, the car gets lifted to such an extent that my low beams at that time are high enough to light up a 6' guy's face coming from the other side.
Moreover with just one person at back, if I cross a water drain, present at any underpass at around 80km/h I get the feeling as if the front wheels have lost ground for a split second.

Correct me if Im wrong.
This is what Im expecting:
"If I change the springs with its old ones"
Since the dampers were totally worn out so the car was lowered from front with suspension getting too soft.
Now if I retain the old springs with new dampers, the ride height will become lower, like it was before but the suspension will not be that soft like they were with worn out dampers.
On hard braking it will not sink into the road from the front, like it did with worn out dampers?

your description sounds like the springs changed the jounce, rebound drastically - which should not be the case, new dampers and springs should restore ride to original. Please verify that these springs are actually for your car.

best would be to reinstall the old ones and test.

If you are losing traction from the rear wheels, check the rear strut, springs and all bushings for wear. Even with a raised front you should not skid out if your dampers are good.

Hmmm...
Thats what I was expecting when I changed them.
Anyways about the rear bushes and springs, I got them checked and there is no issue with the rear.
All bolts tightened and everything is in spec.

Do note that Im using 1~1.5" spacers at the rear and even with them the front got raised.

I was unable to get a picture of the springs when I got them but they were completely straight, unlike the ones that we removed (The were fatter from the middle)
Will get its original springs fitted back in 4~5 days (after Eid) Insha-Allah and will report back.
Thanks a bunch for the information.

Eid Mubarak!

The only plausible explanation I can think of now is that front springs really are of 1.3L vehicle (no matter what the vendor claims).

[fas133]

Gear Oil is leaking from the indicated place.Please suggest solution.

[Xulfiqar]

solution???

replace the oil seal and cover boot.

[usman505]

replacement of seal and boot is the only solution once my car had the same problem replace the seal and clean the
outer side.and its being a year now

[fas133]

A mechanic told me that gear box has to be opened to replace the oil seal.Please confirm is it true.

[agoodfriend]

yeah he is right ,,,,,,,,,,,,,

Okay guys got the springs changed.
Got them replaced with the original ones.
I checked both of them and noticed the original ones were around 1" bigger in length, but were much soft than the ones I got later.
Got them fitted with the new dampers.
The car has returned to its original height.
I took pictures of the car to show the difference.
The "After" picture was taken just after the replacement.
Now after 2 days of driving, it has become a bit more low from the front.
The second picture is of the car on its original springs.

Hmmm...
Yup I think the same as they were quite hard.

[Xulfiqar]

The second picture looks perfect ride height to me, the wheel caster angle is screwed up though - the wheel is pushed too far back or the angle of the picture is making it look like that. Check the lower arm bushing and strut mount.

After driving it for around 100 kms, it has become a bit more low from the front.
This picture was taken just after the fitting was done.
The caster angle is okay, its looking awkward because the steering was not straight, it was slightly turned towards left.

Well I wanted to confirm one thing.
When the original springs were mounted on the damper and were ready to fit in the car, I noticed that the springs were not evenly compressed.
I mean the spring was having a bend on one side as if they were not properly mounted on the damper.
This was the case with both springs.
I showed it to my mechanic and he said its perfectly alright.
What do you say about this?
Is it okay or should they be straight?

[Xulfiqar]

as long as the damper itself is straight you are good. springs will make weird shapes

Ookay!

There is another issue that needs to be resolved.
When I was getting the dampers replaced, my mechanic removed the lower suspension arm as the rubber boot of the end which sits in the chassis mount was damaged.
He checked and told me that the mount needs finishing.
The inner surface of the mount was uneven and bent which resulted in the bent bush, thus damaging it.
I got a new bush and took the car to my denter who was unavailable but his chota tried to do the job.
He grinded the inner side of the mount (Highlighted in blue) and then welded a metal sheet which was cut accordingly.
Then he straightened the other side (Higlighted in red) and tried to fit the suspension arm but it wont fit in because the holes were not in line and the bolt would not pass through with the suspension arm installed.
Now what he did was, that he widened the hole (highlighted in red) just to bring the holes in a straight line.
The suspension arm was fitted but the front hole (highlighted in red) was widened too such an extent that atleast 4~5 bolts can be passed through it at the same time.
He placed a washer over the widened hole and tightened the suspension arm and told me not too worry.
I was not satisfied and on the way back home I noticed that on every speed bump my car would make creaking/squeaking noises at the front right wheel.
Now I'll be going to my denter again to get it done the proper way and I need some help that what would be the best way to repair what that chota has done?

[daniyalahmad]

Plus I forgot to mention that I can feel the car sway in the lane if there is a curve in the road even at speeds of 60km/h.

[Xulfiqar]

fudging around with the arm mount like that - so much that 5 bolts can fit is a sureway to ensure that your caster angle never would be correct. You need to do some measurements now on the otherside and make sure that its completely accurate.

the swaying is also a sign of bad rubber bushing on the arm - if you take it to high speed it will vibrate badly too

Hmmm...
A bolt had its threads stripped, I went to a nearby shop to get a new one.
When I returned I saw what he did with the mount and shouted at him.
He gave me that typical reply: "Nahi nahi gee kuch nahi hota, hum roz aisi das gaariyan theek krte hain; Humara to kaam he yehi hai gee." (Oh how I hate this sentence)
Anyways how can I measure it now and make sure that both holes are in line?
I noticed that there is no visible gap between the suspension arm and the mount on the left side where as on this side there was visible gap between both ends of the mount and the arm end.
