I just acquired an ML 350 a few weeks ago, which had only a few weeks left on its MOT. Upon inspection, it seemed to me that it would easily pass the MOT without any issues. Regrettably, the statement is incorrect.
Seeking guidance with the rear spring failure in my vehicle. Iāve just looked under the back of vehicle and visually they appear good to meā¦.yes there is a fair deal of surface rust, but can you fail a mot on rusted springs? The coil spring has experienced a fracture or breakage according to section 5.3.1.(b) i.
Dealers ask £300 for a set of springs. The cost of labour is £180 per hour. The price of x4 is really high.
Independent are quoted Ā£465 to install 2 genuine merc rear springsā¦Although not too irrational, it does make sense to some extent. Labour Ā£70 phā¦..If they are able to do the task in half the duration of the dealer, which is twice as fast, will I get authentic springs?I remain unconvinced.
Secondly is a problem with the front bearing - failure for excessive play 5.1.3.(a) Everywhere I search, whether it is on forums or online platforms, I come across a method for tightening the bearing in order to minimise any looseness or play. Does the ML 350 4matic truly have this feature?
The price for replacing the front wheel bearing is £304, whereas the cost of the bearing alone is £78.80. Therefore, I presume they anticipate the labour to last around three hours.
Now strangely after dealing with the dealers they have given me a quote of Ā£226.20 - which is the bearing with a new hub (it says the tech guy that both are necessary for the work in the handbook) so now wondering why the independent didnāt include the hub? Only the bearing...which I am uncertain whether it is the cause of the issue - particularly if I can slightly tighten it to successfully pass the MOT.
In addition to the fact that changing rear springs can be accomplished at home with no difficulty, resulting in some cost savings, if the independent mechanic is installing authentic Mercedes springs for £300, I have no reason to complain about the two hours of effort required to fit them.The amount is £465.
Regrettably, the same cannot be said for the bearing. It is not a task that can be readily accomplished inside the confines of one's house. One may find springs for sale on autodoc and Ebay at a discounted price compared to authentic Mercedes ones.Is the authentic product superior in quality? Is it necessary to do the hub installation simultaneously with the bearing?
