The hosts are sitting just outside the bottom four, while the visitors are three points adrift in 23rd position.
Match preview
Wealdstone may be hovering outside the relegation zone, but only goal difference is separating them from Boreham Wood in 21st position.
The Wealdstone hierarchy opted to dismiss manager David Noble following a heavy 4-0 defeat in Saturday's away meeting with Boreham Wood.
Sam Cox, who was subsequently placed in interim charge, was unable to prevent the Stones from slipping to a fifth consecutive loss in Tuesday's home match against Southend United.
Manny Duku found the net in the 33rd minute to give Cox's side a slender lead, before goals from Nathan Ralph and Cav Miley helped Southend turn the game in their favour.
Wealdstone will have to quickly pick themselves up for another home outing, with the hosts looking to claim their first home league victory since beating Halifax Town at the end of January.
As for Dorking, they will have to produce a strong finish to the campaign if they are to have any hope of extending their two-year stay in the fifth tier.
They are currently in a perilous position after failing to win any of their last eight matches since beating National League winners Chesterfield Town at the start of March.
Although they have found wins hard to come by, Dorking have at least managed to earn a point from both of their last two matches.
Marc White's charges salvaged a 1-1 draw in their away meeting with Aldershot Town, before they played out a goalless affair in Saturday's home game against Altrincham.
They will now turn their attention to Thursday's away trip, where they will have the chance to complete a league double over Wealdstone after recording a 3-1 victory in September's reverse fixture.

Wealdstone forward Duku will have to be assessed after he was withdrawn in the early stages of the second half against Southend.
Sean Adarkwa could be presented with the chance to start if Duku fails to prove his fitness in time for Thursday's fixture.
With a short turnaround between games, Cox could be tempted to freshen up his midfield with Jake Young and Max Kretzschmar.
Meanwhile, Dorking forward Jason Prior is a doubt after he was forced off inside the opening 20 minutes of Saturday's draw with Altrincham.
Alfie Rutherford replaced Prior at the weekend, and he is likely to start on Tuesday if the 35-year-old is unable to take his place in the lineup.
Sebastian Bowerman could be recalled to the starting lineup after he was introduced as a half-time substitute at the weekend.
Wealdstone possible starting lineup:
Dewhurst; Barrett, Cook, Barker, Mundle-Smith; Young, Henry, Kretzschmar; De Silva, Allarakhia, Adarkwa
Dorking Wanderers possible starting lineup:
Male; Philpot, Craig, Hollis, B Taylor; Kuhl, J Taylor; Muitt, Carter, Bowerman; Prior
We say: Wealdstone 1-1 Dorking Wanderers
Both teams will be desperate to claim the spoils in this crucial relegation six-pointer, but with the two sides finding wins hard to come by, we think that they could end up playing out a draw at Grosvenor Vale.
