Speed bumps - what damage?

Message Topic Search Topic Options Post Reply Create New Topic Printable Version Translate Topic

   I hit a few of the really narrow sharp ramps yesterday (on the way into 

Hilltop Quad) and something under the car was banging off the ramp also. I 

went over really slow and it seems that when the front suspension 

compresses the car hits the top of the ramp. Went over a little faster on the 

way out (like 5mph) and the car didn't bang off the ramp but if felt a lot 

harder on the suspension. Poxy ramps.

	When I bought my 320 coup� I didn't think it was much lower than the 318 saloon it replaced but a couple of speed ramps have made me guess again. I do slow right down for them but in a few cases not enough. I hear a horrible thud as the suspension is compressed when the wheels reach the bottom. I haven't had a chance to crawl under the car to see what part is meeting the ramps, maybe I don't want to know! So, two questions I guess: 1. Is this normal for an unmodified E46 320Ci? The only way to avoid it is to stop when the front wheels are atop the ramp and eeeease down the far side on the brakes. 2. What is it that's hitting the ramps? It's very solid, so it's not bodywork. Is it a ball joint or wishbone, or am I hammering my sump and working toward a monster bill for sump, oil pump etc. at my next service? Posted here because of the wealth of knowledge and the fact the 3 series technical board seems to move slower than an asthmatic tortoise. Edited by milltown
