Title: knocking
Post by: mcgee9t2 on 08 January 2013, 14:26
Driving along then started hearing a loud knoking. sounded like the front O/S wheel was going to fall off. pulled over and cheked wheel nuts. all tight.

any ideas?

Going to jack the car up tonight and give the wheel a woble try see if its a bearing.

other things ive thought of was top mounts (how would i check to see if its them)
arb bushes ( has arb removed, i know. not the best idea i know. but its how the car was bought, didnt actualy notice no arb till i changed alloys. the cars too low to take corners fast atm anyway. will be getting raised and vrs arb put on in next few weeks)
wishbone bushes ( from a vishual inspection they all looked fine anyway to check)

cheers for any help.

Ok drove home and knoking still there. when i push down on the wing you can sort of feel a clicking type thing and hear the knok so defanitly susp related ide say. gonna take the whel of and have a look in a few mins. have a feeling its top mounts. just a bit strange that its gone from fine to making a loud knoking noise in the matter of a few mins. hmm

any other ideas?

jack her up, take the wheel off, check all nuts and bolts are done up tightly. but tbh could be a number of things coilovers, top mount, wishbone bushes, track rod end or ball joint

Just had a little look online see if i could find anything about seeing if topmounts are worn.
f
irst thing i found said jack car up and lift wheel if top mount rises then there worn. but i always thought there was ment to be some vertical play for when you turn? Can someone confirm this.

also someone said turn steering wheel with wheels on ground and i will see the top mounts move and creek?

Anyone know if these are ways to test? And if not anyone know a way?

cheers
