OK guys, please bear with me, as this might be pretty difficult for me to explain so that it's understandable...

As mentioned in my other thread, I've just installed a set of BMR adjustable LCAs, and during my first real drive afterwards, I experienced a really weird handling issue that I haven't heard anyone else ever mention before...

While traveling down the highway, once I got up to about 60 mph, it felt like the rear end of the car started... "rolling" (for lack of a better term). What I mean by that is that the entire back end felt as though it was traveling in a rotational pattern around the axis of the driveshaft (i.e., if you were to drive behind the car as it was doing this, then judging by the way it felt from the driver's seat, you might have seen the rear of the car traveling in a roughly circular motion starting at an arbitrary point -say 12 o'clock- and then proceeding around the clock face, either clockwise or counter-clockwise - I can't remember, & I was a little bit freaked out by it...)

I'm planning on getting back under the car & making sure that the LCAs are tightened down really well before I go anywhere again, but if anyone has any thoughts on this, I'd sure love to hear 'em...

Now I haven't driven it since that day, I've been waiting to have some time off when I can have someone else verify it from outside the car. Also, the highway that I was on had some fairly deep ruts (& I'm running 245s on the front & 255s on the back), so I'm sure that that played a part - but has anyone else heard of or experienced this?

(Someone tell me that I'm not crazy!!)

sounds like your panhard bar isnt hooked up

Well, I can definitely dbl-check that, but since that & the torque arm are stock, it would surprise me a bit...

But hell, weirder things have happened I suppose...

yeah no doubt when i pulled mine odd it almost had an s curve in it i dont know if someone smacked a curb with the car or what but it had a good bend to it. maybe it rusted through or something? if anything the car should handle better with sfc's it makes the suspension work instead of the body flexing to compensate, which only gets worse over time.

Haven't had time to crawl under there & look at it again yet, but I should be getting the SFCs installed within the next week or so...

sogabe

let me know how thing goes
and if the LCA itself was the problem..

what it sounds like to me as well, since the panhard bar is responsible for the rear's lateral positioning. You may want to look at it's bushings, as well as the panhard mounting point brace since they could also be the culprit. Post up your findings.

Good one MR. Rumble!!!

Thats a good one Sasa. So did a bolt fall out or just loose. Good thing we didn't go up to Mt.Evans with it like that.

HEY MR. SMARTALECK!! I told ya that the bolt in question had loosened itself - I even pointed out the grease on it! Now I WILL admit to not measuring them sufficiently, which was probably part of the problem - I guess I was wrong when I tried to make each side the same length as the original stamped pieces... (But what the hell, it runs great now - thanks again for the assist!)

But I think that you & I maybe need to make a junkyard run one of these days, see what kinds of treasures we can find (like the seats you scored!) - and while we're there, I'll grab another couple of LCA mounting nuts, & DOUBLE-nut those puppies!!

(And we won't even mention the 'Hey, my car's running crappy - oh wait, these vacuum lines are loose!' incident that SOMEONE had recently...)

No, nothing wrong w/ the LCAs, the directions that came with them said to add one pump of grease through the lube fittings, & I may have added a bit more than that, not sure, but there was grease on the threads of the bolt that came loose.

I've only put about 20 or 25 miles on the car since adding the LCAs, but if they've added any road noise it's certainly not a noticeable amount, & now that the two "gremlins" that I had have been banished, it seems to ride very much like it did with the stock units. I might have something to add further down the road, but at this point I see no reason not to recommend that you get them..
