If anyone has personally replaced theirs i.e. done the job themselves, could you be kind enough to assist me on this.

On Tuesday or Wednesday this week I am removing left and right lower control arms and replacing same (bushes replaced).

In the workshop manual it states not to tighten up the bolts until the wheels are placed, car lowered to the ground and bounced up and down about 3 or 4 times to find its level then you can tighten the bolts to torque specs.


Problem......car is on the ground, there is not enough room to swing a cat neveralone to get underneath and try to tighten bolts to torque specs.

How do you go to overcome this?

Maybe I can place car ramps under both front wheels once arms have been replaced so I can tighten bolts to torque spec as above.

Any help on this wouild be welcome.

Cheers, Peter

yep, if your using jack stands you could also just jack up the controll arm untill it just lifts the chassis is lifted off the jack stands. Lots less screwing around

Thanks for your message tx5_brent but it's not that clear to me.

Do you mean I should jack the lower control arm up until it just lifts the chassis off the car stands and then tighten up the the lower control arm bolts to torque specs and the same for the opposite side. Is this correct?

Cheers, Peter

The only thing I read in my book about upper trailing arms and watts link is straight forward, replace bushes and tighten bolts / nuts to torque specs...says nothing else unlike the fronts

According to the other book I read you will need to lower the vehicle to ground level and tighten to torque specs...this for lower and / or upper control arm.

I'm lowering mine onto car ramps , as long as its all level then it should be fine.

Watts links is not critical...just make sure left goes in first, then the center link then install right hand side.

Aparently the left rod needs to be set to left curb???? Then when all complete lower car

Hope this helps you, still a learning curve for me.

all bolts should be tightened at curb height,when you go for wheel alignment tell the guy,he will loosen and re tighten them on the rack,easy for him as the cars level.

his raised rack or ramp,some are almost 1 mtr high and he has all the tools,mine does.i rebushed the k frame and swaped them,tightened the bolts and drove 2 ks to the wheel alignment place,told him the k frame and castor kits in,he loosened all the nuts,settled the car to road height and tightened the nuts up,then wheel alignment.other wise the bushes are under tension.

Yep, I thought that would be the case.

I need some additional advice on removing the lower control arms.

I noticed the bolts are long and unfortunately the steering rack is in the way and also one of the metal coolant lines at the front.

Question.

Do I need to completely remove the steering rack to allow the pivot bolt to removed freely? If so, how is this so as the steering rack seems stuck fast to the aluminium cross member.

The other pivot bolt is near the radiator so will need to lower steel cross member to remove front bolt and remove lower control arm...is this correct?

Cheers, Peter

ok , now - to take lower control arms out , rear bolts can be removed with the rack in , you steer the rack to 1 side and slide out that control arm bolt and repeat on other side .
the front bolts are tricky , once you got the nuts off you need to use a long/deep 18mm socket and remove the 4 nuts ( 2 per side ) ,
once you done that use a crowbar / lever bar and try and slide the front member down far enough to slide the control arm out then repeat for other side .
this is how i did mine when upgraded my series 1 AU to BA/BF front end .

Thanks, I wish I had this information earlier. I had the car jacked up and had taken discs, brakes, hubs off the car and was stuck as how to remove the rear bolts on the lower control arm. I had spares ready to replace as they were rebushed so I decided to do the discs, hubs and brakes instead.

I have upper and lower control arms, shockies and coil springs to do also at the same time.

I'll tackle this again next week.

Thanks again for your assistance.

Cheers
