As some may have read already on another thread, I upgraded vom stock-suspension to BMR. This swap was initiated by 2 problems:

1. Problem: the lower control arms were badly rusted and I feared that they might break on the next streetbumps. Here's what the better one looked like:


2. Problem: I sometimes had the impression like my car was a little tilt in the front. Not much, only a few centimeters. So I measured both sides with the car on even ground. Here's the result measured on the fenders. The frame reflected this imbalance.

As soon as I had pulled the left suspension off the car, I discovered that the bushings only looked good, but the process of dismounting showed that these bushings were there, because they had no way to go. The pictures speak for themselves I think.

BUT the one thing that bakes my noodle is this:
If the bushings on both sides were this bad, and the control arms heavily corroded, could this really induce a serious drop of ride-height? The reason I am asking is not only the obvious tilt, but also the fact that lifting the car in the front with a carjack and then putting it back kept the car about 2-3 inch higher than the actual ride height. I do understand that there might be an inch for normal "play", but here we talk about 2-3 inch. And the last "drop" only came once the front suspension starts moving over uneven ground.

What are your thoughts and experiences about this? :)

Wow, that must've made some massive cluncking noise down the road. The raised height after letting the car down is quite normal since the front suspension cycles through an arc travelling up and down. So if you let it down, the wheels are still under stress and have a lot of camber. As soon as the suspension moves by driving the wheels can "stretch out". Think of it as an old dog strechting his bones in the morning.
As for the difference, I would check the springs. Maybe one of them broke the last coil or so many moons ago, or they're simply worn uneven.

That's what makes it incomprehensible to me: no clunking noises at all while driving :wtf: a few weeks before I pulled it all out, the car started to scratch the fender-wells at the front when going over a bump. but still no clunking noise... The coil springs were visually intact, but I replaced them as well, even the shocks ^^

So, even with the new shocks there's still a height difference?
What about the rear? Do you have a chnce to get the car on a scale and get the weights on all four corners?
Also check the frame for fatigue.

No, not anymore, the vehicle is now even with the new suspension, as is the rear. I haven't road-tested it yet (winter time-out), but i am hoping that the car won't "drop" so far anymore, now that brand new bushings, control-arms, shocks and springs are installed.

They don't have a Ruler in Luxembourg, they have a Grand Duke which is not related to John Wayne.....:cool:
But he's just as cool. By the way, he is also know around here for being a gearhead :D
